Long time Session Buddy user here. I'd like to be able to right click on a link in a folder, and cause the folder to split into 2 at that point.
This would be useful in helping to manage/organize tabs. It would also be useful for folders containing a large number of tabs, where you might only want to open some of them.
Seems there is a Chrome extension
https://split-tabs.com/ which can do something like this. Haven't tried it; not sure whether it is the same as the one from way back when which did this and only this to the active Chrome window.
