cool, but grouping would help Rated 4 out of 5 stars

this addon is a must for me, thanks a lot!

What I'd like to have is also possibility to have
Grouped by Sort/Threaded/Unthreaded, as everytime I change sort criteria (not via this extension but clicking on any column header), grouping is forgotten and I need to set it manually again.

This review is for a previous version of the add-on (0.1).
