 - fix ugly hacks
 	- don't assume apps only have one (relevant) activity
-	- figure out a way to avoid hardcoding resolution, at minimum allow setting it on launch
+	- figure out a way to dynamically change the resolution of a GLSurfaceView
 
 - implement more stuff (there is a lot of it, and it won't get done if nobody helps... ideally pick a simple-ish application and stub/implement stuff until it works)
