Oh that's great! I've read a bit about Bull Bitcoin, but I haven't really dug into yet. Their payjoin feature sounds really cool, but its functionality will be limited to other Bull Bitcoin users. I don't believe there's any other wallet doing payjoin yet, and I'm not sure if it would be compatible with other clients if they did institute payjoin. We'll have to see how it plays out. I'm sure there will be further development in the coming months, and I'll be following its progress closely.

Minibits is a great choice for a zap wallet. It's got a lot of features, and its well coded and designed for maximum usability. And you get the benefit of both lightning and ecash, so you don't need multiple wallets for each. I'm happy hear that found something you like, and which works for you.
