You're going to drop the Extension here too, that is, just NotificationType,
right?

[James Cook, 2014/07/30 22:36:34]

Yes, this will become NotificationType (in namespace extensions).

These are copied in order from chrome_notification_types.h to make it obvious in
this diff that I got them all. I was thinking of alphabetizing them in the final
CL. Do you have an opinion?

[sky, 2014/07/30 17:31:40]

If you look in chrome/browser/chrome_notification_types.h you can see how we've
logically grouped things in certain areas. This is nice from the perspective of
minimizing where you might have to look for something.

We've gone with sorting of preference names. I tend favor grouping into
logically related areas, but I don't feel strongly.

[James Cook, 2014/07/30 22:36:34]

I'll stick with the existing order, then, as it has logical grouping.
