Filter for unread emails

[bedhub]

As a user i want to have the option to filter my email list so that only the unread or read emails of that list/folder are shown.

AC

• there is a button inside the mail list toolbar that allows to set a filter on the mail list to only show read email, only show unread emails or to deactivate the filter
• if you click select all while a filter is active, clicking "select all" will only select mails that match the current filter
• if more mails are loaded while the filter is active, the filter also applies to the newly loaded mails
• same with updates coming from outside: if new mail arrives in the list, it's only displayed if it matches current filter
• filter should be available in the search view  (it should possible to use it in the mobile view)
• as soon as a set of emails is loaded the filter is applied and the matching results are shown even if there are not enough emails to finish loading.
• if there are not enough results, loading continues
• while emails are loading a progress item appears as last list item.
• there is a cancel button on the progress item in the list to stop the loading.
• when loading is cancelled the "show more" item appears.

URL is updated correctly

What does "correctly" mean?

Network errors are handled correctly

Again, what does "correctly" mean? Also, which network errors, other than being offline, and how to I trigger them?

URL is updated correctly

What does "correctly" mean?

• URL is updated every time you switch between folders or mails and only once per switch
• it remembers the mail per folder
• it remember the folder that was open before leaving mail view
• in multiselect the element id part is removed from the URL

You can trigger network errors by breaking the connection, either by actually disconnecting or by using devtools (only works in browser). So yeah it means offline.

It should stop loading and show "load more" button and it should be able to continue when you press on it.
