* https://braintool.org https://braintool.org This looks great, btw. I have been looking for an open-source replacement for Tabs Outliner[0], which helps me effectively manage tabs when there are hundreds, even over a thousand tabs open. There are surprisingly few options that are as powerful. Tabs Fern[1] is a close approximation, but it's tab trees aren't multi-level, and it can only restore entire windows instead of single-tabs. On Firefox, the most powerful tab manager I've found so far is Session Sync[2]. It doesn't seem to scale as much as Tabs Outliner and has a different mode of interaction, but I've been happy with it thus far.
