(Since we're on the subject and since it's easy to throw suggestions in the air

)
What about letting the mouse have a paintbrush-like behavior? Since that's not possible with the Pads section, at least the TechnoBox area would give some extra functionality.
Currently, clicking on one of the trigger areas ("virtual pads"?) in TechnoBox will trigger the instrument as expected, but if I hold the mouse and do a drag-like movement to any of the other trigger areas, they'll stay silent instead of being triggered as the mouse cursor hovers over with the mouse button held down.
...btw, these trigger areas, currently, will light up both on Pad Note ON and again on Note OFF. This is a harmless behavior (flashy lights are always cool

), but I just wanted to point that out if that's not by design.
