It worked ok. Very nice functionality and a good user interface but then... it lost all my sessions (something about "cannot write indexedDB") which is obviously not a good thing for a session manager. Taking into consideration that my sessions where actually not that many (maybe about 10-15, about 400 tabs each spreading to 4-5 windows) to cause serious lagg or memory issues that is a serious failure. There are several files in the extension folder but I cannot find any documentation on any way to get back my sessions or at least my previous ones before the problem occured.
I dont see the developer replying either here or in github and this makes things worse.

P.S. Update 2 years later...New bug.. Tab history (back button) is not saved. Finally moving to a more reliable extension.

Its a great extension. It has almost everything one would need for this. The only thing it's lacking a bit is features for organization. One that would help tremendously is making the search function include tags. E.g if I search for "Plant Water & Food Needs" and a saved session includes the tags "plant" and "water", then it would show up in the results. I know there is the tag dropdown list, but that's only one tag which is not sufficient for proper organization.

I would like in the settings to not save pinned tabs.
Or, when saving, I want to be able to choose whether to include them in the save.

This extension has high memory usage.
