I already gave praise to this plugin, and I still like it, however, I'd like to report couple of things:
• [major] I'm joining other users to report that restored tabs sometimes just go to (seemingly) random URL (some other tab), and the history is lost for that tab. It is really annoying!
• [minor] Using TreeStyleTab, upon restoring session, the parent tab is transformed in a sort of an empty "folder" tab which is like a placeholder for its children tabs. I don't mind this much, but it's unusual.
• [minor] Using https://github.com/nyordanov/panorama to group tabs, the restored session will restore tabs as if they were in a single group.
Otherwise, thank you for your hard work on this extension!
