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.

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.

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.

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

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.

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

(a tool to view dwarffortress's forts)

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

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

• ImageMagick
• Ghostscript
• Pandoc
• LittleCMS (CMS: Color Management System)
• Wireguard
• Rclone

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.

I understand why it doesn't exist because it's pretty niche and a shitload of work, but I wish there was a a really good dedicated 2D animation software similar to Moho Pro or Toon Boom Harmony on Linux. That's one of the only reasons I'm still keeping Windows around.

Also as a side note, don't trust Toon Boom. I bought a perpetual license from them that was super expensive, and then they switched to a subscription model and turned off my perpetual license.

I don't have a concrete idea for you, but I suggest starting with something really simple. I think simple games are a good place to start. Or create a front-end for some command line tool to make it easier on beginners. That way you can focus on the UI development you're interested in without getting bogged down in the rest of it.

A part of the desktop GUI that opens git forge stuff for installed apps. Like I want to just right click "submit code issue" for an app and have it open a proper templates issue for that given project. Right click and select "see source code" and it pops open my ide of choice. Add some integrations for building and installing forks and branches so I can test my changes in real time.

Paint.net for Linux. Most of my experience with making art digitally came from paint.net and there's not really a good alternative that doesn't require me to recreate my workflow from the ground up (Krita).

Pinta is technically an option, but it's missing many of the features that modern paint.net has.

For now, I have to make do with a VM to run it.

I'd be happy to see one more email client option. Using Geary now - nice ui but very limited in features. Been through quite a few in the past.
