Minor Feature Request - Split coins into nearest fixed size + some change #251
Description
The coin split feature is awesome. If one wants to split coins into a specific size it can be a bit fiddly on workflow. Do math in head, enter divisor, hit split, realize you're bad at head math, hit cancel get booted back to entry.
Simple request - a back button to go back to the Split screen from the Confirm Transaction screen or perhaps merge the screen into 1.
Fancier request - split by target value. If you want $100 used coins, enter the $100 target and it calculates how many $100 coins it can make plus some change. If that's because of programming stuff you could alternatively do some approximation.
