CloseReview for Topic Tree / Notebook and Wiki in TB by Anna
Rated 5 out of 5 stars
Is this no longer working? It's exactly what I'm looking for, but can't find a way to access it after installing. No buttons, menus, or anything after searching everywhere...
Edit: Never mind. It takes restarting Thunderbird multiple times (at least on MacOS) for the icon to show up. Other than that, it works smoothly, well done!
