Rated 4 out of 5 stars
I can only confirm that after update to ver. 6.6 I cannot see any options on Account/Identity Colors tab in addon-options window - only blank tab under it`s name.
In version 6.5 everything was OK.
Version 6.6 should have been fixed as soon as possible.
Fixed in Version 6.7
This problem is fixed in Account Colors 6.7.
