holding ‘shift’ and selecting more than one face, is often not recognized.  
deleting objects take forever  
the refreshing of the menu on the left hand side takes up to 1 second.

e.g. when I try to subtract an object from another object (see video):

- I select the first object (0:49)
- I click 'CTRL-B ’ and select the second object (it’s now 0:53)
- Shapr3d understands what I’m trying to do, but the selection of the objects is lost (0:56)
- I reselect the objects (it’s now 0:59)
- Shapr3d confirms that I can do it, and shows the “check” button (1:01)
- I click the “check” button (i’t’s now 1:03)
- nothing happens…
