Thanks for the suggestions @mindtrap. I just added them to the list of features we're considering for V3 & 4.

A few of those operations (i.e. sending tokens, powering up, claiming accounts with RCs) are available on the "Wallet" tab. You just need to login with Hive keychain (at the top right of the screen) and you'll see the buttons there. You can also create accounts with your claim tokens and download the keys, etc. ;)
