Linux

A universal uninstaller.

Now that Ubuntu has apt, snap, ~/bin, flatpak, appimages, etc, when I want to disable, update, or, uninstall an app, I can't quickly figure out where it is or how to do that. So a program that starts with 'which appname' or something more clever to find it, which also told you what type of installation method it was and then let you remove it with the next action.

For example I had Desktop Docker installed which was garbage, and I didn't remember how I had installed it. In that case you couldn't use 'which' because that's not the name of the executable, so you'd have to design something smarter that could search .desktop files or whatever.

Good luck with your project!

There is not much choice for drawing diagrams, dia is old school and draw.io is big.

A standalone utility for decoding QR codes that will work on a desktop. All I want is to be able to put a picture of the code in and get whatever text it was concealing in a little text box where I can read it, and C&P it if it's useful to do so. If something like this exists, I've never been able to find it, although there are seemingly dozens of programs for generating QR codes.

GUI for Pipewire configuration. Being able to reliably change the sample rate and buffer size without having to mess with config files would be nice.

I wish Stonesense was better and more stable. Im just glad it is still maintained though.

(a tool to view dwarffortress's forts)

GUI for managing fingerprints/PAM that allows complicated or at least some customization with PAM such as requiring password on first login then allowing graphical fingerprints for sudo, unlock and other prompts with fallback to password.

Three finger drag in Wayland, a new gui for opensnitch where i can isolate network activity by app like little snitch 

I wish there was a graphical or CLI option to add a Linux drive to etc/fstab.

A graphical 'advanced' package manager for Qt / KDE. Something to replace Muon which is/was the KDE equivalent of Synaptic but no longer available in Kubuntu. Discover shows you apps (both snap and apt), Muon showed packages with all sort of relevant technical information (source, dependencies, 'reverse dependencies', installed files). I guess everything Synaptic/Muon does is also available through the various apt subcommands but there is value in a decent GUI to bundle those individual commands and their output.

Qt version of cool GTK software: Nicotine+, Ardour (ahahah), Lutris, Cartridges

Qt software I would love to see graphically improved: QuodLibet, Falkon, Qbittorrent, KeePass

Others: PeerTube client, Syncthing client, Ardour+Kdenlive fusion (a good Video DAW is my wet dream), Lemmy for desktop

A real Photoshop replacement. GIMP is cool, but ain't it. I have yet to find ANY software that can replace PS. I've even tried using multiple programs to replace PS, and it just doesn't work. I fucking HATE Adobe.
