Reply to LaunchPad Mapping for Traktor Pro

Hi all.
I've started making a mapping for my LaunchPad with TraktorPro.
Here are the pros&cons :

Pros:
More buttons than a midifighter.
LED buttons that we can use to show tempo/sync (really nice)

Cons:
Less feeling than with a midifighter.
No knobs so controlling volume/fx/filter is possible but might be painful.

My question is :

If I have to finish this mapping, what would you like in it ?

1) Only play/loop/sync/cues

2) A bit of Volume/Eq control

3) Something else (you tell me then)

Please comments welcome I'd really like to offer this to you along with a lil video.

Peace
