Last q. Can I make 3rd party packages for Lightworks, Resolve or uwsgi? Or how can I get these tools on Solus?

I do not understand. Installation steps were provided. And v14.5 will be shipped with portaudio, so no workaround is required. Is snap/flatpak required?

Personally I'd like to have access to core packages at the lowest level (maybe from shell only). Core/OS packages should provide stability and always successful upgrading (no dependency hell, etc).
Using UI I'd like to install two kind of programs: a system services (like database servers, http servers, app servers, etc) and end-user applications (gimp, darktable, etc).
Dependencies for apps should be solved by flatpak/appimage, and dependencies for services should be resolved automatically (under the hood).

I've manually installed Lightworks in Solus 2017.04.18.0. It seems to work well.

Josh, yes I realize that. Just wanted to share my 2cents. I like the idea of selling & purchasing a software, that's why I've wrote my thoughts. Sorry again for an OT.

This is an off topic, but I want like to say something...
