Save/restore tabs on switching between git branches

Is this request to save/restore tabs automatically?
I ask because on my testing, switching between branches (in GIT) and restoring tabs, doesn't work.
The saved tabs entry shows but selecting it, does nothing.
When I go back to my original branch (though I didn't commit anything) the tabs restore again.
It makes me wonder where the files are stored.
