Another good email client. Many are trying to leave Thunderbird on GNU Linux but there aren't many to choose from.

A self-hosted photo/video viewer which presents itself as an Open Directory that maps closely to the underlying file system and also includes the ability to view images and stream videos. If videos are too large/incompatible with the user’s browser, they should be transcoded on the fly (optionally with the gpu). Genuinely surprised something like this doesn’t exist

The EU managed to get Meta on their knees with GDPR. They could force unlocked bootloader and easy install of any OS on phones just like on laptop/pc. I believe then we would really get the Linux phone movement going. Imagine: iPhone with UBports.

Proper 3D CAD software, we have FreeCAD but it isn't very good.

Open source language learning only has Anki. Everything else is in an enbryonic stage.

There are so many low hanging fruits. Add-on to look up words in subtitles and add it to Anki. Luo dingo clone that's a bit less tedious (without having to write so much of your native language). Clozemaster clone (unless someone knows how to set up Anki to do this)

Most anything related to healthcare:

• System for medics and nurses to input all the data of a patient, which can be accessed by said patient if need be
• System for keeping track of vaccines applied and pinging people who need to take more shots (second dose, reinforcement dose, etc)
• drivers and programs to interact with medical equipment

I'd like a local filesharing option. Where a single folder would be synced in my phone from home computer when I'm at home, and from work computer and phone when I'm at work. Without using cloud sync between them only when I'm physically traveling between them, that's good enough for most use cases of cloud sync that I want for work.

At the minute, a true open source and free browser/web engine, though I know this is nigh impossible to maintain without thousands of people. Some part of me is hopeful though given recent events.

I'm always surprised that, for as widely used as PDFs are, there doesn't seem to be any real alternative to Acrobat for editing existing PDFs.

Nothing and everything.

There are thousands if not millions of open source solutions scattered around society. Some are feature complete, most are not. Some are maintained, many are not. A handful are funded, the rest is not.

What open source needs, more than anything else is fundraising and the means to distribute those funds to the tune of the trillions of dollars that the corporate world extracts in profits from those open source efforts.

In other words, the people who make this need to get paid.

Firefox terms and conditions, Red Hat, and several other projects that have caused uproar through the community, are all caused by the need to get paid to eat food and have a roof over your head whilst you contribute to society and give away your efforts.

A high performance RISC-V CPU core.

games! in maybe 95% of cases you can find an open alternative to some (non-game) software, but with games it's the opposite.

i would say that the main proprietary softwares i still use, are video games

A mesh network internet, it's more of a hardware, security, and adoption problem but at this point there's enough wifi overlap in most residential areas that entire towns could have their own local internet without needing the ISP model at all.

A printer or printer firmware. There was a discussion about this elsewhere on lemmy, of course this would be difficult and expensive but it would be very cool

Openly available traffic data that follows a reliable standard.

for me the most critical ones are replacements for discord and microsoft teams. for discord the critical piece is the login - people don't want to make accounts on each server, so until we have proper federation with a good user experience people won't actually move off it.

for teams i'm sure theres projects in development, i just don't know them or their status - all i know is that i want a project to combine several specialized FOSS services (jitsi is great, and there's lots of other collaboration tools for email/calendar/chat) into one nice unified frontend that is actually reasonably easy to self-host and maintain.

A. Phone.

A project to give me money in exchange for me writing software.

Tax software. It's the only reason I keep a windows VM.

A fitness tracker app that rivals Strava.
