I know this may not be Arturia's thing, but I think a drag & drop sampler would be cool.
Rather than extensive editing to keymap "one shots" you could just drag the one shot sample directly to the key used, for one off bits like special effects, narrations, etc.. Loops can be dropped to the pads, and then back to the normal Arturia format for the rest.
Ideally, I want to be able to use an Arturia application in conjuction with a Roland PK 5 or 6. Just scroll through presets for a Taurus pedal preset, and then song specific stuff with one shots, arpeggiations, drones, pads, etc... If this could then be dropped into an iPad, then the Arturia loaded iPad connected to a PK 5 or 6 would be a very powerful foot controlled device.
