@dolik-rce :
I think part of this is already present in some plugin ("auto save" or something like that, I'm typing this from phone). It saves modified files periodically in configured directory. It just lacks a nice way to restore the previous states. And yes, I'd love to have this feature 👍
AFAIK the `save_actions` core plugin saves a backup in the configured directory, but it still saves over the file as well, and it doesn't save the path of the file or any metadata, and it doesn't save buffers that are not file backed.
