Two categories, broadly: any professional software, with deep features and professional quality.

I know theres audacity, but that's really not an acceptable saw.

I know theres a few cad apps, but no professional I've ever met finds the good enough.

I know gimp, and I use it, but no artist I know does; they all pirate Photoshop. Literally every one.

I like having audacity to record audio. I like having gimp to fuck with shit. I like having various cad apps to bang out organizational tools to print. These things do generally fit my use case. But I still have to help people pirate everything else and god the DRM is do fucking annoying.

Abd here's the more esoteric ask:

Not so much programs as features; Why aren't we really going all in on shit we can do that they can't? Features capitalists would never add, never support? Instead I find open source software always playing catch-up, and theres no reason it has to.

Krita & OpenToonz handle just about everything I need as an animator/artist, but I'm worried about OpenToonz continued development. I worry that there aren't enough people working on it.

I sometimes needed something like powerquery from microsoft excel. To like quickly get specific data from a structured file.

Notion + OneNote/Samsung Notes

There is a myriad of open source notes apps, but none of them really hit the spot for me.

Partiful / evite. There’s not much out there that’s a good simple replacement.
