Great! Very usefuly
A suggestion for a new feature: option to keep tabs is one more click away, it's a long process, it would be useful to have a button, and some way to suspend/unuspend/keep tabs by group (for example selecting multiple tabs at once or based on multi-account container)

I would like to see an option to establish a maximum number of inactive tabs on a per windows basis.

Ex: Maximum of n inactive tabs for any given window.

I find myself having this issue that I left some tabs opened in a random window, and the addon keeps unloading the tabs on the window I'm working on because it exceeds the maximum I have setted.
