Can you setup this configuration like the image

Position should be right-aligned to Sponsors. If you have any ideas than suggest.

Not getting good response from the users ( in emails, reviews etc)

[auxves]

@shanalikhan I should be able to finish it today, but it might take a while since I'm currently away from home.

How about we put the checkbox pinned on the bottom right of the page. This way it's easily spotted. It also doesn't have anything to do with sponsors.

[shanalikhan]

Yes, go ahead. Do share the image.

There are some improvement that can improve the UX.
What are your views about it. We can ship these improvements with v3.4.1

1. On Startup
   When user click on Login with Github and click on skip button. There dialog should be appeared to user that GIST is not configured, Settings Sync will create new GIST on Upload.

2. On Upload
   When token and GIST is not configured, page does open along with the warning of invalid GIST.

   • Invalid GIST error should not appear when GIST is empty.
   • When user gets the token and select any gist. It should start the upload process automatically as User is coming from On Upload process.
   • If user click on Skip button, it should start the upload process create the new GIST as User is coming from On Upload Process.

3. On Download
   When token and GIST is not configured, page does open along with Invalid GIST error.

   • Invalid GIST error should not appear when GIST is empty.
   • When user gets the token
   • On Gist Page, Skip button should be hidden as user wants to download, instead we can show close button to stop the process.
   • When user select any GIST, it should start downloading process as user is coming from On Download process

4. New Github user.
   If there is no GIST available to Github user attached. Login to Github does not show anything that it has fetched the token. We need to show that screen everytime even there is no GIST attached. ( tried to new github account)

5. Transfer the Github Application ownership to my account (@shanalikhan).

Error:

I have disabled the check.
Now when Settings sync isnot configured, on upload it doesnt open the configuration page to setup, instead gives error of invalid token.

Can you fix it when possible i'm looking to release new version.

I have fixed this check.

You can include the things discussed here #960 (comment) and one more thing in PR.

i-e
The Show at startup is always checked, we need to bind to its current value. To show unchecked if not checked. When opened via upload / download process
