I understand the concerns of ZCG but I think this application of Zcash is something I’d still like to see explored. I cant speak for ZCG but for the price the lack of a web version is a concern.
I think until we have access to a browser based wallet (e.g. zephyr?) I’d argue we delay any duplicate effort on private key management. I have no idea if this would sway ZCG in anyway but would a react-native-web version with view-keys only be possible within the scope of this project? Also providing users the ability to provide links to the web view etc?
Just my 2 zats as a potential users
