Yeah I quite like the idea of an "Array group". Sounds similar to some of the generator objects in Cinema 4D where you place an object as a child object of a generator object e.g. Array object or MoGraph cloner object. The settings of the Array object or Cloner object can be adjusted any time.

Object grouping is probably the number one thing for me.

A few things like the menus need expanding so you don't have to keep adding scripts for everything. e.g. incremental save

I would also like more flexibility with windows. Sometime I want just 2 windows e.g. top and perspective.
