get customable workspace with multiple views and in perspective views rotation by right-mouse and on 2d views panning by right-mouse, zooming in/out with ctrl+mouse, in other words, look at Rhino3D. small plants lab is also something i would like to see. easier selection of objects proberly by using multiple layers (Rhino...). more rough brushes in the terrain editor, the kind that makes chaotic stones/cracks etc' sorta like mounds. better sclaing tools (Rhino again...) that's it for now, maybe i'll think of more later.
