The only problem that I have with TSM is that it does not play nicely with Simple Tab Groups at the moment. I use STG all the time, so unfortunately until this bug is sorted, TSM is a non-starter for me. Which is unfortunate because it is highly recommended and I would like to use it. (P.S.: I run a Mac using Monterey so quite old, nevertheless, this post is accurate as at 2025-05-08.)

Works really well. I would like functionality to name windows and have that title persisting after saving and restoring a window or session. I'm using extension Window Titler that prefixes the name of the window with [MyTitle], followed by the name of whatever tab is currently open (so window title changes dynamically). That functionality is perfect, but that title is obviously lost when window is saved.
