can you explain more about what you want?
but let me also just explain where i think taptap fits in to the world of hotkeys and macros.
there are some great hotkey/macro tools (like autohotkey, macro express, lots of others).
so i dont think taptap should try to do what they already do, and some of them surely can be used to do advanced stuff like doing certain things when certain programs are running.
so i think taptap should limit itself to stuff it can do reallly fast, that other programs can't, like catching the double tap stuff.
now having said that, i'm open to the possibility of saying that a double-tap in one program might send a different key than a double tap in another, since it wouldnt impact speed nor be very hard to add.
