This is the most useful ext. I am privileged to use. Having many windows open due to ongoing projects, this makes reopening them so much easier and faster when you have to reboot (though I usually just hibernate). This is akin to the session saver ext. for Firefox, and it would be good if Windows itself had such a thing (not just reopen folders, so I use AutoHotKey to launch related apps simultaneously). If this could be configured to save multiple sessions it might be even more helpful. 5 stars as it is. Thanks and may God bless.
