One thing that I love on it, Find all unused assemblies and remove.
Basically if I have code that would bloat my application on compile and it is not used, it finds and removes it.
I would love to have a tool that finds all unused Sounds, Sprites, Objects and just gives me an easy list to pick and delete some.
For those who say i'm just bing lazy, I'm getting to the point where it takes me awhile to sort through it all.
This becomes pretty important when we talk about mobile downloads etc.
