Have you noticed that the plugin interferes with the Sweet Home 3D UI after usage? The scrollbar handle (between the 2D and 3D views) and the 2Dview grid have changed after closing the plugin window.

The navigation click+drag with the mouse is unchanged and still turns the wrong way, both left/right (rotate) and up/down (tilt).

I didn't notice the free draw selection area before, a very, very useful feature. But... area selection still includes elements behind the select area. In other words, if I select the front of a sphere, the hidden faces at the back are also selected. That makes the area select virtually useless. Area select should only select the visible elements inside the drawn area.
