Great Tip! I hadn't noticed that.
I am having one problem with the Keychain in 10.2 that maybe someone could help with. I have it such that the keychain locks when the machine goes to sleep.
When I wake up, I usually have mail and ichat running, and each of them prompt me to unlock the keychain. Both had previously been given "Always Allow" privileges. The bug appears to be that waking from sleep, every keychain app asks you to unlock the keychain even though it had been unlocked a few seconds prior.
This never occurred in 10.1. You would unlock the keychain on wake and every app would be happy.
