Show the next code on the same line when current code is about to expire

[vrubleg]

There is an option that always shows the next code, but it takes a whole line. I would suggest mix both "Indicate when codes are about to expire" and "Show next code" in a way that as soon as a code is about to expire, a new code fades in on the right of the current code. When current code is expired, the new code slides left on top of the old code.

That's what I proposed in #923. Unfortunately, the developers didn't understand the request, since they seem to always tap the code, which freezes the current token.

The implemented "show next code" doesn't solve the original problem for users who like to avoid that additional step of tapping/freezing the current code:

• small code is hardly readable
• code jumps to a different position and different text size => no simple way to continue with the second block after entering the first 3 digits and then coming back
