Guys, just a suggestion but there seem to be a bit of an inconsistency between the way Friends and Messaging plugins notify users about new events. Consider the following screenshots:
Messaging plugin seem to update it's menu item using WP's update classes to notify user about new mail, while Friends simply lists current number of new requests.
Considering how tightly integrated this two plugins are, wouldn't it be nicer if the Friends plugin updated menu item similarly to Messaging plugin? It would also prevent users from overlooking friends requests when email notification is disabled.
