Thanks a lot for this! Just wanted to point out something and maybe make a suggestion:

I had six windows open each with some tabs related to a specific task. Used OneTab on one window and then tried to use it on another and it looks like the window just closed. Took me a minute to release the OneTab tab was on another window and another to find the right window. Not sure if this needs to be fixed or anything but maybe allowing a OneTab tab on each open window would be less confusing.

As for the suggestion, it would be nice to be able to give each tab group a name instead of just showing the number of tabs. Could be useful on the shared web page as well.

Thanks again!
