As I enter a Name in the Advanced Editor, the title should change synchronously
Summary: This needs sanity-checking, but seems likely to be correct
Pointed out by Alexx: when you see "Editing Model .38isjdu", it isn't obvious that changing the Name field will affect that.
The change from "Display Name" to "Name" may help, but probably isn't enough. Having the h1 alter as you type would make it much clearer.
Alternatively, you might be able to click on the h1, and edit the Name directly there? That would be more Googlish, and Alexx expected it to work.
