I really love Nano, but a huge issue it has is the privacy one: I don't feel comfortable to pay in a shop or send money to friends using Nano, because they'll see all the amount of Nano I own. *(edit for clarification: my concern is not the wallet balance shown on my smartphone, but the fact that who receive the transaction can search my address on a block explorer, and see all my transactions and the balance).*
I see on GitHub there's a [proof-of-concept of a Nano wallet with privacy feature](https://github.com/LilleJohs/Nanonymous), it basically use a disposable address every time you want to receive a transaction, making it similiar to what Bitcoin wallets usually do.
Unfortunately, the app seems not working (I guess their server is not longer online), and I didn't find any alternative wallet.
Why are a feature like this is not implemented in Natrium or Nault? Why people seems don't care about it?
