Tab Session Manager has a feature that saves a backup file to a designated folder in the downloads folder every time Chrome starts up.
I'm pretty sure this shouldn't be too hard to implement in Session buddy, and this will be very useful. I know you're working on a remote cloud save, but it's been in the work for so many years and i don't think it'll come any time soon. And in the meanwhile, Session buddy just auto-updated back in march 2019 and deleted all my saved session and auto-saved session for the past 2 years before march 2019, so this is frustrating, that session buddy loses sessions out of the blue for no reason, a problem that many people have experienced.
I hope this local Autosave backup to downloads folder could be implemented soon, or something like it, cause we really need it.
