App Shortcuts for frequently used accounts

As an expansion on this comment: #100 (comment)

Using App Shortcuts, it would be interesting to explore adding certain frequently used accounts to the home screen so you can quickly tap, copy the code to your clipboard, then swap back into the app you were using.

Of course, there are a couple ways this could be implemented, and listing every single OTP account in the shortcut dialog is not a good option (as I've got 10s), we could try:

• Detecting frequently used accounts
• Adding an explicit option under an account dialog to add to home screen
• ...

I'm open to feedback and would be willing to work on this
