If any dev is looking for something to do on Nostr, I would highly recommend improving the nostr zap button. This one thin has sooo much potential, I can't stop thinking about it!

For instance, you could create a user friendly front-end UI where a person can customize their widget style, widget placement, type of widget (slide out, pop out from the bottom placed button, etc...), button styles, embedded analytics options, additional button options.

There is so much that can be done with this, which could help nostr adoption significantly in the long run.

In fact, I think this thing alone could be its own business. Someone just has to tackle it and see it through.
