Sessions directory is cool.
Because i'm a slow learner, i've only just realised there's been a change in Snapshot's & Stable's directory structure that i really like. It's way cool.
I never used to know where my manually-saved Sessions were stored. Now however it's easy, & good... /home/steffie/.config/vivaldi-snapshot/Default/Sessions ... similar path for Stable.
Not only does this facilitate easier targeted backups, but it also allows simple post-save session renaming [& copying between Stable & SS]. Nice.
EDIT: Hmmm, looks like most of the above is a load of hooey, & i'm a galah. I just fired up my old Linux Lite VM that i've not played with for a long time [double-digit months i think], which has V-SS v1.5.658.3. It also has the dedicated Sessions directory. Oh well... i still think it's great to have, only it appears not to be new at all...
