Dolphin:

1: Greater modeartor functionality
2: Improve builders, you cant change every single page
3: Admin Panel: Ban IP
4: Privacy, Users should be able to block people from contacting them via messaging, and also block people from viewing there profiles
5: Installation, more granular, select options to be installed as some dont need the whole package.

Ray:

1: Ability to block someone from viewing your video feed.
2: IP BAN function
3: Greater admin controls, delete rooms / moderate see more etc / invisible mode, so admin cant be seen in chat
4: General asthetics, make the cam blocks more rounded and professional looking, it all looks a bit clunky at the moment.
5: Default room creating, when first launched the chat should have a room, it currently doesnt.

Im sure I could think of 100's more little things, but these are the nuts and bolts.
