I've found Local History on these JetBrains IDEs to be really helpful too. Particularly when combined with "Put Label" command (which I assign to a keyboard shortcut). This lets you insert a descriptive label info the stream of your local history snapshots (such as before you attempt something), so you can go straight to one of those labels and diff against current. Useful when you're trying out an approach with parts that may be discarded, as it's handy for reverting lines of current or overwriting and inserting blocks back from the snapshots. You automatically get a label after certain events, like a test fail or VCS commit. I think there's a snapshot after every save too, and you can configure autosave to happen whenever the editor pane loses focus of you want to.

The only things to watch out for with local history in these IDEs is that the snapshots are deleted after five days by default, and all are wiped if you need to delete your IDE cache for any reason.
