Same, it's saved my butt so many times. Once in the middle of a tech conference, I was messing around in the terminal with my networking and borked something really bad.
I spent 5 minutes trying to get my networking back but couldn't figure out what I had screwed up and ended up breaking it more.
I just went into Timeshift and restored to the beginning of that day and in a few minutes I was back up like nothing had happened.
