Sounds like great improvements :)
However, here's a little bug: I'm currently importing new characters from MagicaVoxel, and after saving a couple of them without problem, the editor crashes without warning when I try to save a new one. I didn't do anything special, just importing, adding a few tags, and saving. This occured twice in a row, not sure what may cause this.
EDIT: Apparently this happens less often if I close each model before importing a new one and/or if I save the model empty first. But it still crashes after 4 or 5 imported models. Could it be a memory related issue?
EDIT 2: This occurs even when I don't import models. Adding tags and unchekching "walkable" then saving is enough to cause a crash.
