For me, Google video search, Google books (Internet Archive is good, but doesn’t always have the same stuff), Adobe InDesign (but in the process of learning LaTeX), and Typewise. As for the Google stuff, I liked Whoogle a lot, but almost all their instances seem to have been blocked or shut down. Also, apologies if this is repeating an earlier post.
I wanted to package an ambisonic VST3 plugin as a Flatpak, really need to learn that as this would make things really easy.
But I have no idea of audio production, find it really cool but its a complex topic.
