There are some bug fixed in the last time:
- glitch free rotate and action for rotate asks mouse-down to perform it
- extrude works in 1 click to pick the face and you can drop
- after extrude the current extrude is selected in tree and in properties view for easy change
The current extrude have some issues not because of extrude code but because of selection code bugs. I will work to track them down.
All other 3D actions that change the scene will be selected in tree that expose the shape to you, after you create them for making your usage easier.
