Rated 3 out of 5 stars
What would be a really good option to have, is if you could group similar tabs together by Primary domain, without sorting the entire bar by alphabetically by domain.
eg. If the first 2 tabs I open are from Sony.com , the tabs would group together by hostname, but if i open two new tabs from Amazon.com, they would still group together by domain, but remain in their location on the bar (last) without jumping to the left.
This would fix the issue of tabs moving around constantly as you open new sites.
Also, if grouped by primary domain only, this would stop them jumping around if I change from forum.sony.com to sony.com/download.
