I still use this plugin often and find it very useful.
I just discovered something that could be improved though.
When you use the compare tree to propagate changes from one side to the other one, some of the changes are reflected in the changes tab, and some are not.
More precisely the actions done using IDEA diff viewer are propagated to the changes, but not the "copy right file to left" for example.
Would it be possible to add it to the changes too ?
