wish if there was help file or tool-tips when you hover over settings. Some add-ons have it and it is very useful.

If you are using always tabs over 10, you MUST install this extension.

Works flawlessly. Essential when working with multiple tabs open tabs on projects with multiple aspects. Tree level management saves a lot of time, keeps active tabs organized, and helps avoid closing tabs still in use by accident.

Best addon i found.
For multitabs.

ótimo aproveitamento.
