First order of business for the new subforum:
What are some of the free open-source software you like to use regularly?
Just about all of my daily stuff is open source: Firefox for browsing, Thunderbird for emails, Blender and Krita for art stuff, the usual run of the mill you'd expect.
But for some of the more "out-there" choices:
Zim-Wiki, which I use for general note keeping as well as organizing commission info. It stores notes as plaintext on my OneDrive, so if I ever need to reference my notes outside of Zim, I can open it in any text editor. (btw highly recommend getting an app like this, definitely watch this video for suggestions https://www.youtube.com/watch?v=XRpHIa-2XCE)
HexChat, an IRC client that I've been using lately to get a feel for IRC chats. I've found myself to be a regular user on the Furnet server, though like any IRC chat other than LibraChat, it's fairly quiet.
Kodi, which runs as an OS under Libre-Elec on a Raspberry Pi, which acts as my media center where I watch all of my downloaded media.
I was going to suggest Foobar2000 as my offline music player, but that isn't open source unfortunately. It is free though, so if that's of interest to anyone, go for it!
