This is a very good question !

I would like to see a web place listing all users features requests for various bitcoin apps, or even developers PRs where people can vote / fund them with sats directly.

Like a direct crowdfunding PRs.

Do you want X new feature to be implement? Good, post your proposal, describe it well and put a bounty on it. Other users if they find it useful, will zap more sats. If a developer wants to do it, could claim it and when is done, will take the sats.

Fiatjaf had something like that and Blixt Wallet use it for a while.

In this way all open source software can be funded directly and users will have a voice too.
