I would love to see more functionality for organising variables displayed in the inspector.
For some complex FSMs I have over 40 variables I need to control and it can get quite messy. Right now I'm using suffixes & prefixes to try and organise them but it still things aren't as managed as I'd like them.
I would love to be able to group variables into hierarchies, create some separators, colour coordinate, label certain variables etc etc.
I know these things are easier said than done, but this is just my $0.02
