We're quite often building floorplans, seating layouts etc in Capture as part of the "Sales pitch" for events. One feature that woule be really helpful would be a simple "Door" library item with user adjustable height, width and opening direction. 

In plot and wireframe views it should have that traditional architectural style symbol showing the arc of the door and direction of swing. 

Currently I end up flipping between sketchup and capture every time and it's a pain.
