Hi compitus, welcome to the forums.
Unfortunately there are a great many applications that don't use the AeroSnap function. I think it's due to the resources required & the internal workings of the app.
I've just tried a few & it looks like mainly 'folder' & 'browser' based apps/environments will utilize AeroSnap. It's a case of trial & error when trying application with AeroSnap i'm afraid.
Hope this helps
Jeff
