Previously, to create a copy of a Standard Wall was done in a roundabout way that not all users were aware of. (by pressing Add, then selecting from a list of Standard walls). To make it more evident, we added a Copy button to allow you to copy an existing Standard wall. You must make at least one change to this standard wall before it can be saved.

The old way of copying a Standard wall still exists alongside the new one for those users who are more comfortable with it.
