First off I salute the dev team for the great work you guys make. Your baby has a great potential!
What I'd love to see is more conventional UI. I mean could it look like 'normal'
1. Orbit mode (similar to the Sketchup \Max etc.)
2. user defined Shortcuts for ALL operations (it's the fastest way to work with PC)
3. SU\ACAD components\blocks support, with ability to select all the instances and replace 'em
with lumion stuff.
4. Eyedropper to take material from one object and assign to another.
5. 'Save' command?
6. 'Undo' for the the multiple operations
7. Drag'n'drop materials\library entities from the modeless windows.
