yesterday i had a closer look to TSM and got a clue how it works and what features.

i also had tab-saver installed and dismissed it now.

but what i miss is an import export feature like tab-saver. maybe not for separate sessions but for all sessions would be nice.

another point to mention is the UI design - i would prefer it more clear, eg:

1 Window, 1 Tab | Open | Delete
(2017-10-19 11-12-13)
Window1
(fav)(tab)

i had a closer look into and that is possible when positioning the div elements in another formation. ofc the css need a polish to fit again.

translating may be more complicated because many strings are hard coded and some are only notify(e.message);

PS @Jacob - running perfect on b9 and now b10 - new window all stored tabs. try a new profile

4* because import/export ;)

a proudfull replacement for legacy "session manager" - wonderful job.
