Is that what nostrdesign was recently set to be doing? There surely can be a generic approach because all nostr apps share the same onboarding etc. that comes from the protocol fundamentals.

But on the other side, if we were to fund/design/build the best in class client including UX that’s possible on nostr, with a great design system - all other devs will want to at least copy the way it works. 

Can open the design files and a design system for other to copy and adapt. 

The work can include User journey maps, basic design heuristics in general and examples from best in class apps so solo devs are better equipped not to make obvious mistakes that hurt UX
