Code review comment for lp:~mzanetti/unity8/dash-as-app

See inline.

Now, on DashCommunicator... I was wondering if we should instead register a scope:/// url handler, and then just dispatch scope:///clickscope/ when needed.

Only tricky part would be on left edge, when we should bring the dash in from the left with your finger, url-dispatcher would request focus, but we should ignore that request then.
