The chat interface is some of the most contested real estate on the site and everything must work in concert at various screen sizes including mobile. Using hidden buttons that appear on hover on top of the video makes the best use of the real estate leaving other spots open for things that change based on show types, special promotions, etc.
The admin reply makes sense to me especially the part of leaving the space above & below video open for things that change based on the show type that's happening in the model room, the contests, promotions etc.
The previous & next room arrow key, for easy access to click quickly, has to be mainly either below the model screen or as an unobtrusive hover on either side of their screen. That's what I notice in many popular cam sites. If the tab's gonna be one of the buttons on the right side, it's gonna be choresome to click on, atleast for me lol unless they keep it right on top when you open the panel. I think those who actively been using such feature(in flirt or other sites) including me prefer not only the randomness but also the easy access to click quickly from one room to the other.
