Several inadequacies with the dice app. Especially on small phones.

1. No "invert selection" option
2. no ability to change size of totals, and unreadably small on a 3" diagonal screen
3. no ability to change size of dice - the symbols are too small on the dice on my phone as well
4. back button does not react properly (neither on my Samsung Note 12" not my LG Pixel.) - it does nothing I can detect in this app.
5. I have had issues using the set-face on ring dice.

And on the would be nice:

1. ability to change dice colors (at least for standard dice).
2. Ability to set difficulty (perhaps as dice-like tokens?) that get canceled out.
3. ability to set a "spindown die" - a d20 that never rolls, but only gets changed by direct interaction - this would be VERY useful for tracking current Wounds and Strife.

Otherwise, pretty nice.

I'd like it to auto-keep any dice you just exploded by default. If you end up exploding 3 dice it can get tricky to remember which dice should be selected to keep.
