One kind of a recurring issue is how to create the frameless corner windows, using just a mitered glass connection as below:

Switching to the Custom Corner… tab page of the Window settings however doesn’t allow us to choose Glass, but Frame or Corner Column only.

The trick is that glass connections are only available for one type of window, the Horizontal Multi-Sash Window. Switch to this one and change the Corner Connection Type accordingly.
