Linux

LibreOffice (the UI seems to be much better on Linux vs on Windows), Firefox, Thunderbird, Tauon (the only music player I could find without iTunes era UI and has a usable shuffle function. Gapless/G4Music and Amberol are slick GNOME apps, but shuffle is terrible on both), Joplin (for notes), Okular (PDFs), VSCodium (code editor), Godot (game engine), ES-DE + RetroArch (for emulation), nomacs (images), Celluloid and Clapper (video player), FreeTube (YouTube client), OBS studio (screen recorder), Aseprite (pixel art, the editor I use the most, very awesome!), GIMP (photoshop, don’t really use this one as much as I never really used photoshop), Inkscape (illustrator, this is the editor I use the second most, it’s awesome), RawTherapee (Lightroom, I will eventually learn how to use this, but I am putting it off right now), FreeCAD + Blender (3D modelling), Kdenlive (video editor), OrcaSlicer (3D slicer), Nextcloud (self-hosted file backup + a bazillion other things), Immich (self-hosted photo backup), the default Calendar app w/ Radicale (finally I can sync my calendar with my phone! You aren’t able to do the same thing with the def. cal. of Windows…), Steam (all the games I play are supported), and a bunch of CLI utilities as well (like yt-dlp).
