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)

Good for saving resources without needing to close tabs completely. However There seems to be a bug with the way the "Discard All Other Tabs" function works.

It appears to respect the whitelist and blacklist features of the addon like auto-discarding does. I suspect that this isn't the intended behavior, because discarding tabs using "Discard Tab" ignores the lists. This is what I expected with "Discard All Other tabs" because it's being done manually just like "Discard Tab" is. Because it doesn't ignore them, I initially thought that this function just didn't work at all.

If it is the intended behavior for "Discard Tab" to ignore the lists but "Discard All Other Tabs" to respect them, it should be more clear about that. I'd also like the option for it to ignore the lists just like "Discard Tab" does, since I feel like this makes more sense, and is more useful.

The only other problem I have is that putting a discarded tab into focus automatically reloads the tab. This is pretty inconvenient and I'd much rather have the tab stay discarded until I manually reload it, or something like that.

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.
