Added to Purge Data section in Quality Control some tools - https://i.imgur.com/Nz3YoiH.png
1) Print unused elements - useful to investigate how much unused data you have in IFC file.

2) purge unused elements by ifc class, it's doing it in pretty naive way and can be dangerous, so maybe it should be moved to debug section.
Error was:
TypeError: EnumProperty(..., default='cobie'): not found in enum members
Exception in module register(): \3.6\scripts\addons\blenderbim\__init__.py
Traceback (most recent call last):

Decoration data is now updating in live time, caching some parts in Data for performance. Real time update is needed because Data doesn't allow update on objects positions change and later will need real time update for viewport orientation data.
Now OverrideDuplicateMoveLinked allways will be in sync with OverrideDuplicateMove.
Also fixed the issue when DuplicateMoveLinked for non ifc elements worked the same was DuplicateMove (it was copying mesh data when it's not suppose to).
I think there is still some space to improve but it should cover the main problem with need going to array section to remove it
