Hey Tappy... how about a checkbox on the top-left of the screen, that, when checked, sorts the boss list on "best buy"?
You know, most DPS for the money, so I don't need to scroll through the list to see which boss gives me the highest increase in DPS
When you click on the next level button while beating up an enemy, let it end said enemy first before going to the next level.
And let level progress be saved if you skip back and forth between levels, instead of having to start from 0 again.
