I don’t use a whole bunch of software honestly, so it’s pretty easy to remember everything. I’m also dual booting still for a bit, so my windows partition has all the software too. All my games are on an external hard drive (I mostly play older games so the slower speed of an external HDD doesn’t really matter too much).

Adding to this, I’m a new Linux user, and I’m distro hopping a bit. I started with Mint, now I’m currently using Bazzite (basically Fedora Kinoite with some drivers and apps preinstalled for gaming to basically be plug and play), but I find rpm-ostree to be more confusing than whatever Ubuntu is based on so I might switch to another Ubuntu-based distro. It’s fun to discover what you like best though, so OP if you’re reading this, that’s my advice as someone in the same boat as you. Bounce around and see what works best.
