Stopped displaying currently open session tabs, and doesn't show Save button unless full screen. It also started opening its own tab and using that generic non-descriptive tab name as the save title for every save. Don't know why this has changed. Pretty well killed it for me.

This extension has been very useful. It has saved me a lot of times when I had accidentally closed a window full for tabs or when the browser crashed. Thank you!

Doesn't show any currently open tabs.

Man I love the cloud save feature! I thought I lost my sessions after erasing my PC but then I remembered to sign in and sync from the cloud. Awesome!

Has the potential to be(come) great, but for now not useful - for me.

You cannot drag closed tabs to different window.
You cannot drag windows to a different session.
Sessions can't be organized in folders.

Tags for sessions are useful, as you can filter them. This is nice.
Auto-track change option is also a good idea, but it has to be activated for each session individually - it seems.

For now it seems a good extension for people who want session syncing for sessions containing multiple windows.
People who want to sync WINDOWS (1 window = 1 subject) will find this extension less useful.

always have been the best since years... Thanks a lot for all the time you make me save !!
