koshiua: that's just ONE feature of bartab. The most important feature for me is that new tabs opened in the background DO NOT load which keeps firefox fast and memory footprint low. Unloading of tabs (manual and automatic) is also an awesome feature that no other extension has so far that i know of.
If only someone could take over this addon and update it and fix any remaining bugs.
