No worries, I thought that too, and initially bought staff's argument that they couldn't support two things - until Kirkburn said that visual and source are two completely different editors (hence why there's space at the bottom of the edit window in visual, but not source). Therefore I see no reason why source mode can't have the old layout (which is better suited to source editing), and visual mode can have the new layout (as that's what the layout was primarily designed for)
