Why are wallets the biggest concern that people at the conference keep hammering on? I'm watching the startup pitchday video another user posted and it's been several wallets already, plus I heard a number of speakers on the other stages tell people to "build a better wallet".
I don't understand. What are the features that are missing? What more does a wallet need to do that hasn't already been done? I've sampled a number of lightning wallets so far, and one seems as good as any other to me. What am I missing?
