A very bad idea... Making the camera controls floater resizable means making it a true floater, with a title bar, which also means making it bigger. Plus, there is no need to make it larger, since it already got all the needed space for the existing camera operations.
Implementing a front view is something I considered already, especially when sitting your avatar (many seats are against a wall, and the rear view is then inappropriate since it's blocked by the wall)... Since there's some room left in the camera controls (under the draw distance spinner), I might well add a "Front" checkbox, there...
