Cool, thanks. Another use case other than backup I was thinking is if just wanting to share a window of tabs (so all relating to a project) by copy/pasting it to someone in a message/email; I guess on flip side too, if person receiving the links also had Tabist then could have another popup to "open links" (maybe there's a way to do that in Chrome easily but I'm not aware); could eventually create a centralized service that just pushes the links to them and perhaps auto-opens them - obvious potential security issues there but arguably person you're receiving links from would be trusted by you.
