Thank you for this addon, it is marvelous. Thank you for continuing support and development!
I would ask for one additional feature: rename tab header. I use a lot of windows and collapsed trees together with Tab Session Manager(to open/close those windows) to keep the information organized and possibility to rename tab header would be perfect to identify a collapsed tree. Your addon has support in Tab Session Manager, so I humbly think they would add support for this feature too.
Thank you very much, once again!
