Wouldn't be great to save all the open tabs, and not only restore them (there are tons of browser extensions that do that), but also treat them as a collection to share, restore in a different computer etc? I built that feature into Histre : https://histre.com/features/save-restore-tabs/ https://histre.com/features/save-restore-tabs/ if you're interested.
