A bigger push/platform/shared-library that would make it easier for developers across Nostr to implement NIPs and stay up-to-date on those.

The problem I see something like this solving is as follows.

I solely use Amber (NIP46) to sign events for me because I find it to be so far the most secure and also convenient method in my threat-model. So many clients are yet to implement or even announce plans to do so.

Worse yet, are encrypted DMs. 0xchat and Amethyst work pretty well together, where Amethyst can do older less-secure DMs, but can also read/write encrypted DMs which 0xchat can also do, but the moment I'm on Desktop/Web browser that falls apart, there is no convergence as far as encrypted DMs (something like NIP44) go, only less-secure ones.
