The app is well executed, looks create and has a good UI (well, except for the alert box when you update your profile).

However, I agree it is a little to MVP. To be useful I need more control over what is displayed in the bar ... and I probably want to host all the scripts on my own server too.

I want to be able to set the content in the Javascript code that instantiates the bar so the message is relevant to a user action.
