Inkscape?

Bitwarden password manager. I've used several proprietary PW managers, Bitwarden is by far the most stable, intuitive, and functional IMO.

TV Headend + Kodi

Emacs and vim are both vastly superior to all other text editors.

Which one you like better is a matter of taste.

Vim is a girlfriend with rock hard abs who wants to take you rock climbing and of whom you're secretly a little scared.

Emacs is a big bouncy happy girl who wants to take care of you in every conceivable way, then split a bucket of RAM while binging pirated movies.

All the Linux file managers I've tried are nicer to use and more stable than the Windows File Explorer.

VSCodium is better than most text editors. BTW, if you didn't know, you can still install some (turns out not all of them will work so you might still need the proprietary build from MS) extensions from Microsoft's store manually.

ShareX is the best software I have ever found for taking screenshots and/or quick gifs/videos. It's a real shame it doesn't have a GNU/Linux version, it's the only app I miss badly from my Windows days. Any other screenshot software is just nothing in comparison with it.

Joplin is my fav note-taking app. I have tried a lot of them but this one just works, has quite a big feature set, can synchronise using different mediums, from Dropbox to using Syncthing and synchronising files locally, doesn't look poorly, is cross-platform, has e2ee, doesn't cockblock you with paywalls. For me it's the perfect note-taking app.

Aegis is the best 2FA app for Android there is atm. IIRC, it got created because Google Auth had some problems with privacy so the whole idea of Aegis is to be the better option.

Lichess — a chess server with no BS and there are 0 paywalls. chess.com would force you to pay for stupid things like puzzles, with Lichess I am able to procrastinate with chess. For free.

NewPipe is the best YouTube client there is. For me, it's because of fast-forward on silence and the ability to unhook pitch and video speed. That means you don't have to either waste your time on literal nothing or struggle to understand what a person is saying anymore. NewPipe also gives you everything YouTube Premium does.

I’ll take LibreOffice Writer over MS Word anytime. All that ‘I know better than you,’ ‘You wanted to copy the space, too, right? Even though you stopped marking before it,’ can kiss my ass.

Calibre vs... em something that's not calibre.

I'm honest not sure what I would use instead, but it would be hard to replace.

KDE is better than Windows

~~Audible~~ Audacity is more audio programme than most people need

KdenLive is more video editor than most people need

Kritta is more art programme than most people need

There are edge cases where there are professional programmes that might be better but unless you are a professional you do not need them and even semi-pros would likely be better served by those three

My Pop!_OS system has never shown me ads for Candy Crush.

VLC absolutely wrecked Windows Media Player. Firefox was the same with IE.

Blender. I feel pretty confident in saying that there is simply nothing like it in the commercial world. Its feature set is unreal; its like the swiss army knife of 3D modelling programs. I can't say enough good things about Blender. It has replaced so many secondary programs in my workflow and is slowly dominating to become my entire workflow.

It used to suck to use in the late 2010s and then work was done to overhaul its space-shuttle cockpit interface, and now it actually feels concise and usable. I freaking love blender now. Big time blender fanboy right here.

I could be biased but 2009scape. While originally a Runescape clone of 2009, they've preserved the integrity of the game much better than the official versions

Audiobookshelf. Way WAY better than Audible

DWM, Newsboat, MPV, NSXIV
