This is rBBS_RothUI and layout style for the rBBS framework. It generates a bottom bar that looks like Roth UI. Supports Roth UI 4.009+ fluid orb animations.
Use the rBBS menu gem or the /rbbs slash command to open the menu. You can do the following things ingame: lock, unlock, show, hide, resize, scale, move, reset.
Version 1.03 introduced a new API function, the dragframe. If you want to make use of it create it first in your layout and have other frames parent it. (See example layouts). If you move/scale/resize the dragframe all hooked frames will follow.
