Are you planning on implementing Sapling?
We have sapling since March

GReat.
How about an Android copay wallet ? Maybe fork BTCz wallet?
Thanks for you suggestion.
BZEdge is already present on ZelCore and VidulumApp. SnowGem's ModernWallet mobile version is coming soon.
BZE has plenty of support on mobile.
Nothing replaces an official dedicated wallet backed by the dev team who will brand it and slowly move it towards a useful payment system.
ZelCore: Where do I scan a private key in? I cant. How do I add my existing wallet with 24 words? I cant. Where is my private key? Stored on their servers and supposedly encrypted until we find out maybe not very good encryption?
We make recommendations that would make the project better. Copay wallet that BTCz team forked to create their branded wallet is open source and proven to be trusted. The private keys are ONLY on the local device.
A branded wallet would be another app to spend resources on when we have so many beautiful options already available.
