Version 4.0 beta
This version is compatible with SweetHome3D 7.2. It hasn't been tested with previous versions (anyway I don't see any reason to make it compatible with previous versions).

New features and fixes:
- You can change the way objects move when dragging in 3D view (from menu 3D view->Pan 3D View settings)
- You can edit the selection in 3D view using CTRL+E (other than double click)
- Reduced plugin size
