Middleman alternatives

Hey, the app is great! But I want to add my 2 cents to make it even greater. It would be useful to add a contact list and let the users to decide which reciever addresses to save there. Small improvement about QR scanning. I'm using 1Inch Mobile Wallet 2.1.2 for iOS. I want to send some USDt to an exchange wallet. I open the wallet and find my USDt balance in the list then tap on it. On the next screen "Send USDt" I scan an exchange deposit address. The deposit address is added to the "public address" but the coin I plan to send is set to ETH. Why? I selected USDt on the previous step. Hope you'll fix that.
