I'm OK with these names and I like that the app_shell_browsertests code is in a
file named app_shell. However, did you consider naming them all just shell_*? 
That's what I've done with most of the files in apps/shell. I was relying on the
//apps path and apps:: namespace to differentiate from other Shell* classes.

Ok, will just call them that.
