Does running in app mode trigger session restore? If so and nothing is restored
I suspect you'll like a CHECK. Can you test this.

[zel, 2013/01/30 22:55:16]

Nope. No session restore needed for this mode.

[sky, 2013/01/30 23:29:56]

But this runs on chromeos which automatically triggers session restore, right?
Is there an early out some where else that avoid session restore for this mode?

[zel, 2013/01/30 23:56:57]

Nope, we won't trigger session restore in forced app mode. I am working on
startup/shutdown changes for this mode in another CL - this part was only
covering UI tweaks.
