Comment 6 for bug 1486031

The "default" page layout (when no kicad_wks is specified in the Eeschema/Pcbnew Page Settings dialog) is hard coded in:

common/page_layout/page_layout_default_description.cpp

meaning you can't edit the default (unspecified) even if you wanted (I believe that's what you meant @Wayne?).

IMHO this is incorrect and instead the template (new) project file should specify the installed kicad_wks file in the template directory (or suitable alternative). However this is a bigger change that might mean the majority of older KiCad projects that don't specify a kicad_wks file (currently the default) are displayed with no border at all in future versions?
