Great! First addon that allows me to minimize tabs and gives me the exact tab workflow I'm used from opera 12. Will continue to use this.
There is minor drawback that it doesn't seem to respect the insertRelatedAfterCurrent configuration, at least I couldn't get it to open all tabs to the end of tabbar (like I have it on opera).
Extra thanks for the shortcut functions, combined with firegestures I now have minimize tab mouse gesture.
This addon didn't work well together with the tab mix plus addon (which I then removed as I find this addon more usefull).
