Basically what IntelliJ calls local history. It is a feature that has saved my bacon. https://www.jetbrains.com/help/idea/local-history.html
Yes, I concur. Local History is wonderful; nice to see Zed getting its own version.
Ooooh, this is cool. I was unaware of this. Thanks for the link.
Similar, but not as polished, also exists in VSCode and derivatives, named the same way. Definitely saved me a few times as well.
