As the move is much more presets driven than say, the push, or standalone Live, it would be nice to have an ableton-sanctioned library of community provided presets. There would of course need to be copyright concerns with samples, but it would be great for a centralized place to browse and download new presets.
This could take the form of a web library browsable from ableton.com or linked from the move web UI, or even browsable from the device itself.
