Very excited to find this app! Just started using it and have a couple of suggestions right off the bat:

• The Logout - login to add another account is a little counter intuitive (I know it makes sense to those very familiar with signing and Keychain but not to newbies). Would strongly recommend you add something like "Add Another Account" to the UI.
• This is a request: link two accounts. One of my projects posts with one account (in a celeb name) and usually replies with an administrative account. I'd love to be able to see all comments left on the celeb name, but reply and manage from the admin account.

This is definitely an app I will be using going forward.
