I'm vaguely naive of programming... I have no agency in that world, beyond "hello world". How do I sponsor features or apps that I want to see become reality? I've heard of bug bounties, surely there's such thing as programming bounties, right?

most developers are pretty open when it comes to listening to the community. If you have certain feature in mind suggest it to the developers. As for supporting certain app development, just zap the developers or the apps official npub.
