One thing we want to do to improve the UI is to remove the current black topbar and replace it with a top bar that melds better with the app. Most web apps these days have a colored topbar that contains a name, logo, document title, share button, account settings button, etc. In Sandstorm you see a lot of apps still having such a topbar of their own, but then the Sandstorm topbar lives above it, and half of the usual topbar functionality actually ends up in the Sandstorm top bar, confusing people. In order for Sandstorm to defend against app security vulnerabilities, we can't simply let the app handle its own access control, so we do need a place to hang this trusted UI. What I'd like to do is have Sandstorm render a modern-style colored top bar with all the usual elements an app would put in it -- with the ability for the app to customize the color and contents to some degree. This top bar would feel like part of the app, but would be trusted, so we could put access control and account settings there, etc.
