Wallpaper around a window
Short pieces are on by default. Drag the window; open Door if you need one. Strip count still follows wall width unless an opening is floor-to-ceiling.
What it does: Turns on short strips around a window or door so you waste less paper above and below openings.
What it does not: Openings on separate-wall lines are drawn but do not change strip count unless shorts are on.
Limits: Door shorts need the door gate open. Check one strip on the wall before cutting the rest.
Drag the opening. Strips stay full height unless short pieces are turned on.
The opening area of the default window is 16,800 cm². It does not reduce the 8 strips.
