My wishes (some of them have been mentioned in other threads already)

Illustrator Import/Export. (I hope it will be in with V. 1)
Some sort of boolean operations on closed planar curves (for example union ten overlapping circles would be easier than using the trim command)
Text tool
Curve projection (again, we can use the trim option as a workaround but if find this quite tedious...)
Coons and Gordon surfaces.

I think I would be more than happy with these features... ;-)

Then maybe some parametric presets for "special" curves (cogs, stars, flowers, and of course spiral and helix...)

And I agree 100 % with the following :
Object groups, names (and colours !) + option to unhide only selected objects and not all at once...
Closed loft...

So Michael, As you can see, there are a few things to keep you busy for the coming months... ;-)
