I'm not sure if I understand.. I would not like to change my window layout, I would just like to understand how Construct decides where a new layout or even sheet should open. My current layout spans two monitors and is setup like this (from left to right):
Monitor 1:
-properties panel
-big window for layouts
Monitor 2:
-layers panel
-big window for event sheets
-projects panel
-objects panel
Again, I'm very happy with that setup, but when I open layouts from the projects-panel, they open inside the projects panel (I would like them to open in one of the big windows instead).
