This is an Extension for the Automatic1111 Webui, which adds a curtain.
When you don't want the passerby to see what you are generating, just add a curtain over the results that folds away when hovered~
By default, the curtain is folded away on the right. Simply click on it to let it expand. Click on it again to fold it once more.
Did I spend too much effort making the curtains look good?
