Change opacity to rectangles
Changing opacity or selecting a pattern fill to rectangles would aloud to create box dialogs effects, like the one i`m ussing right now to give you feedback.
It`s usefull to indicate that you don`t want to change the context, and you need to capture the users atencion.
Transparency is now available for all stencils that have a configurable color option like background, text or border. Enjoy!
