Just something I thought about, can't be a kind of wishlist, I just wanted to share, to understand how far I am from your expectations...

1. Today's simple UI
2. Full 2D capabilities (dimensions etc)
3. Full object selection, grouping, etc... capabilities. Also visibility control.
4. Complete API for plugin development... Not by me, but a Maxwell plugin would be great.
5. Transformation and history methods using MAX's modifier stack or similar so that we loose nothing.

These are the most important features for me....
