Reply to Mapping ideas

So i have a NanoPad first gen, and im just in need for more ideas in the map i am using. It is to go along side another controller other than cues, loops and basic effects - What other stuff can i add to it, considering i have 12 buttons, 6 and 6, and i may be able to encorporate a shift button so it is 2 x 5 by 5.

Any ideas?
