Anyone have suggestions about how you would go about setting up something like custom "profiles" on the Droid to quickly adjust sounds? For example, during normal operating conditions, I'd like to have my ringer set to loud and notifications also loud, but at night, I'd like to silence all notifications and have my ringer set to low. Sort of a "wake" mode and a "sleep" mode. Make sense? I was able to achieve this on my Blackberry by creating custom profiles.
