Improving The "Roll Dice" Button
After you use it, it always disappears and you have to go through the process all over again. It'd be nice if it would stay up so you can continue to use. Then just X out when you're done.
Also be cool if it kept track of what you rolled before you Xd out. Give you a tally of your results and show up in history.
Would be handy for when you need to edit battles the engine can't do. Having it in History would have a record for your opponent to see.
