Yeah, it does have an option to keep x amount of snapshots. But the ones that took all the room I had created manually. They were from like two years ago and so I clearly didn’t need them (Yes, I’ve been on the same Linux Mint installation for two years).
Learning about new things is the best thing about Linux. I keep a folder with screenshots and saved html pages for all the fixes, workarounds and settings I’ve accumulated over the two years I’ve used Linux on my desktop. Highly recommend keeping a similar folder.
