Is it possible to "collapse" a text note ? I'm reading a PDF document, making handwritten notes. I want to type a long note, with some text copied from Wikipedia, but I don't want to have the text taking all the space. So, is it possible to make the note collapse like a "yellow sticky note", so I can see it is there but not taking all the space. If I click on the "sticky note" it would "uncollapse" so I can read it or edit it.
