There are two important things that were overlooked in the old design that desperately need to be added to the new layout.
1. A "flag this message" needs to be added to the inbox messages design. The spam button doesn't really fit messages that contain threats or illegal requests (for nude or fetish videos for example) or nude videos. Lot's of younger are harassed by creeps who know messages are hard to report.
2. A "block user" button must be added to the page used for unavailable/hidden channels. We shouldn't have to copy the channel name into the addressbook to block it.
