AC15 has a much better range of external doors than AC14 with some double doors (see image), but why no basic double entrance door?
It seems a fairly obvious gap in the library. It would matter less if you were able to switch off the sidelights of the available double doors, but I don't think you can.
If GS prefer to produce a library of similar parts rather than a single fully parametric part, that library should strive to be complete.
