Rated 3 out of 5 stars

nice addon. I'm using it in linux and most of the features seem to work well except:
1. I cant tile tabs to the top by dragging it towards the top panel. the markers dont appear.
2. after splitted windows are regrouped into tabs the window isn't maximised.

..and the sync scroll thing doesn't work.

This review is for a previous version of the add-on (2.0.2011090101.1-signed.1-signed).
