[FEAT] More control over the flashcard ordering

[4Source]

This feature is on top of the #814 should add more control how to go through the cards during review.

I am currently working on it but I would like to here some feedback before continue.

Current Functionality

The new system should consist of 4 drop-down menus which are:
Deck order
In which order the decks get selected.

• Sequential
• Random

Card order
In which order the cards in a deck get selected.

• Sequential
• Random

Deck priority
How the deck order is prioritized complete the deck or only one card per deck. Could probably extended with a random option.

• Complete
• Round robin
• (Random)

Card priority
Which cards get prioritized to complete first.

• New first
• Due first
• Any first

The resulting options are listed here:

Deck order	Card order	Card priority	Deck priority	Explained	Replaces current
Sequential	Sequential	New first	Complete	Goes sequentially through all decks. First all new cards in deck	Sequentially within a deck (All new cards first) & Sequentially (once all cards in previous deck reviewed)
Sequential	Sequential	Due first	Complete	Goes sequentially through all decks. First all due cards in deck	Sequentially within a deck (All due cards first) & Sequentially (once all cards in previous deck reviewed)
Sequential	Sequential	Any first	Complete	Ignores new and due goes through one after another
Sequential	Sequential	New first	Round robin	Goes sequentially through all decks with new cards first only one new card per deck
Sequential	Sequential	Due first	Round robin	Goes sequentially through all decks with due cards first only one due card per deck
Sequential	Sequential	Any first	Round robin	Goes sequentially through all decks only one card per deck
Sequential	Random	New first	Complete	Goes sequentially through all decks. First all new random cards in deck	Randomly within a deck (All new cards first) & Sequentially (once all cards in previous deck reviewed)
Sequential	Random	Due first	Complete	Goes sequentially through all decks. First all due random cards in deck	Randomly within a deck (All due cards first) & Sequentially (once all cards in previous deck reviewed)
Sequential	Random	Any first	Complete	Ignores new and due goes through one deck after the other and gives random card within deck
Sequential	Random	New first	Round robin	Goes sequentially through all decks with new cards first only one random new card per deck
Sequential	Random	Due first	Round robin	Goes sequentially through all decks with due cards first only one random due card per deck
Sequential	Random	Any first	Round robin	Goes sequentially through all decks only one random card per deck
Random	Sequential	New first	Complete	Goes randomly through all decks. First all new cards in deck	Sequentially within a deck (All new cards first) & Randomly (once all cards in previous deck reviewed)
Random	Sequential	Due first	Complete	Goes randomly through all decks. First all due cards in deck	Sequentially within a deck (All due cards first) & Randomly (once all cards in previous deck reviewed)
Random	Sequential	Any first	Complete	Ignores new and due goes through one deck than randomlly selects a new deck gives one deck after the another within the deck
Random	Sequential	New first	Round robin	Goes randomly through all decks with new cards first only one new card per deck
Random	Sequential	Due first	Round robin	Goes randomly through all decks with due cards first only one due card per deck
Random	Sequential	Any first	Round robin	Goes randomly through all decks only one card per deck
Random	Random	New first	Complete	Goes randomly through all decks. First all new random cards in deck	Randomly within a deck (All new cards first) & Randomly (once all cards in previous deck reviewed)
Random	Random	Due first	Complete	Goes randomly through all decks. First all due random cards in deck	Randomly within a deck (All due cards first) & Randomly (once all cards in previous deck reviewed)
Random	Random	Any first	Complete	Goes randomly through all deck when completed with random card from deck
Random	Random	New first	Round robin	Goes randomly through all decks with new cards first only one random new card per deck
Random	Random	Due first	Round robin	Goes randomly through all decks with due cards first only one random due card per deck
Random	Random	Any first	Round robin	Goes randomly through all decks with any card first only one random card per deck	Random card from random deck & Every card a random deck with a random card Ignoring new and due

This should nearly address any possible way someone would like to configure the review at least when deck priority includes a random option. And if there are any other needs I think on this base there could be easily added in future.

I would love to hear your thoughts on this, so please share.

Hi @4Source

Wow. Man, you've put in so much work to get to this point. I've only had a chance to look at this briefly, but had a few questions for you.

Are the "deck priority" and "card priority" headings crossed over against the column content?

I'm wondering if it would be possible to stage the development, rather than adding in everything all in one go.

So I'm curious which options are ones that:

• you want to see because it will be helpful for you
• other users have requested in other issues (I do keep an eye out on most things, nothing immediately comes to mind)
• you think would be "nice to have"

@st3v3nmw might think differently, and in the end this is his baby, but I know that for every feature added it requires more than just the implementation time. There is writing the unit test cases, having it reviewed by Stephen or myself et cetera.

Hence why I'm wondering if it would be possible to stage the development. Ones that are "nice to have" could be moved to a separate issue, and you could see if people comment and indicate that they would use it if it was implemented.

Kudos once again for thinking this all through, it must have taken serious effort!

Cheers
Ronny

Yeah this took a while. I really thought about this a while (couple of weeks now).

Are the "deck priority" and "card priority" headings crossed over against the column content?

Ohh yes there are switched I will fix this.

I'm wondering if it would be possible to stage the development, rather than adding in everything all in one go.

Yes I Think this should be possible. And for sure easier to review. A possible Solution could be to firstly ignore the Round robin options and just implement it with only the Complete Deck priority this would halve the amount of possible combinations. Also the Any first could be set to only be allowed when Deck & Card order are both set to Random. This would only keep the existing Configurations but would setup the Base for the Additional Configurations. Which could be added in 2. stage or any later stage of development.

So I'm curious which options are ones that:

• you want to see because it will be helpful for you
• other users have requested in other issues (I do keep an eye out on most things, nothing immediately comes to mind)
• you think would be "nice to have"

I'am at the moment not happy with the currently available options and thought I couldn't be the only one who don't would like to have more control how the review presents me the cards. And adding more and more Options to the existing drop down would not be really efficient. And would make a later refactoring harder.
I didn't find any related issues, so I don't think others have requested something similar.

@st3v3nmw might think differently, and in the end this is his baby, but I know that for every feature added it requires more than just the implementation time.

This is one of the reasons why I created this issue, to avoid wasting my time implementing something what don't get included.

There is writing the unit test cases, having it reviewed by Stephen or myself et cetera.

Whit the unit test cases I could help and implement them by myself the review part on the other hand I cant really help you only thing I could do add more Comments while going through this.

This is now a lot more but I added a better description of the configurations and the option for random Deck priority. Also give each row a development stage in a order I think it would make sense. For me every thing including Stage 3 is what I would like to have. Stage 4 in my opinion is a bonus but not really necessary.

It feels like I am spamming so sry for that.

• seq: Sequential
• rnd: Random

Development Stage 1

The main goal at stage 1 is to prepare the code to accept further modifications. Only implementing the existing functionallity without modifying the unit tests everything should work the same.

Development Stage 2

Add the function that there is no prioritization of due/new.

New unit test are requiered at this stage.

Development Stage 3

Implements the Round robin option for Card priority.

New unit test are requiered at this stage.

Development Stage 4

Implements the random option for Card priority.

New unit test are requiered at this stage.

Maybe this needs a rethinking here is a order that would be with this setup not possible

[4Source]

I think that in addition to the above mentioned Card order sequential, random there should also be oldest, lowest rating The lowest rating will show cards with the lowest rating first (ease).

---

Also Maybe a solution to reduce the amount of implementations would be if there is no deck order. This would be possible if all Subdecks are combined at the same "level" meaning are contained in the click deck. The Subdeck structure would only be noted for each card, but there is no difference in the order if it was located in a Subdeck or directly in the clicked deck. I think this would also make a lot of sense because if you click on a deck you would like to learn all of the cards inside this deck and if you would like to be more specific "you go a level deeper " and click one of the Subdecks.
