NDK sucks. So much stuff built on it is unnecessarily slow/nonfunctional/out of date/incompatible with the latest nips.

Moving nostr dev OFF of github and apps off of the official stores. The tools to do this exist, but need use/feedback/support.

The lack of basic business tools: calendar, context aware contact databases, streamlined nostr-centric payment systems that are strictly non-kyc and one-click deployable with a relay/server.

Lightning alternatives. I detest lightning as a layer 2. Would be cool to see some new ideas in this space to allow for others, like ark or atomic swaps.
