I think it would be neat to be able to see the descriptions for each instance variable when selected in the properties sidebar.
Right now when I select an instance variable it just says "A number/string/bool instance variable, unique to each instance of the object". Seems like that could be like a right click help kinda thing, or maybe the object type could bookend the description, ie ('Player 1's score is stored here. [number]', 'Name of player. [string]', Whether or not player is awesome. [bool])
Anyway, just an idea.
