Here are my ideas I was thinking about adding but can't find time to figure out how.
If you ever plan to do an official update you can consider them.
[spoiler]Last selected range/break point preference can be saved per word list.(meaning Hiragana word list was last set to 20 at a time, RTK set to use break points, etc.)
Save/keep best set completion time (maybe displayed with timer).
Add a counter for missed answers to display with "Set Complete" or with the timer display. Maybe save "Best=_" (lowest amount of misses) somewhere.
Styles can be selected by unique names instead of numbers.
That's it for now.[/spoiler]
