Wishes for V3:

instancing system.
Ideally the instance could be kept as instances when exported to 3d programs such as modo and C4d, but this may be too much to ask.
Having instances for modeling would already be good.

Groups. I guess this will be coming soon.

Display enhancement.
Especially when I have a lot of lines, from imported plans for exemple, moi really slows down.
Would be nice if we could freeze all lines from one plan into one object.
