Perhaps this is a really silly idea 
, but I was wondering about the utility of having some indicator of what command was just executed. Think of Growl notifications, but for key commands to give the user some feedback of what just happened.
I often find I get key combinations mixed up and I may have executed a command but I have no idea what that command was (other than perhaps looking it up in the default Keymap file). A series of successive commands would stack notifications in some pleasing way, and then perhaps fade out over some short period of time.
Obviously, there would be a way to enable/disable depending on preference. But I really think it might be helpful for people learning ST2 and keyboard based UI like me.
