Using filters and labels has made GMail my tool of choice for productivity, but I'm finding it a pain to have to create multiple filters to add multiple labels or to forward emails to multiple recipients.
While I can set up a mailing list in my Google Apps management console that lets me get around the multiple email address limitation, I don't have any other workaround for assigning multiple labels.
[ + Add another Label ] would be a great button to see!
I would love to see Google Reader become an optional part of the Google Apps package. For the company, everyone on the domain would be subscribed to certain feeds by default (e.g., company news, etc.). For the individual user, it would be convenient to not have to log on to both Google Apps AND the regular Google account to read both feeds and email.
