A grant to develop an existing open source Bitcoin/LN wallet - not a new one, we have already great ones like OBW and Blixt - to support users with different experiences via an evolutive user interface/UX that mix semplicity, powerfull functions and didatic in a single tool that adapts to the user grow.
This could help because the newcomers and the "experts" will share the same wallet, so the later can easily help the former. Wallet diversification is important, but a this stage joining the forces on a unique tool could boost the adoption.
