I use a Mac, but thought this was a general question... Is there a way to control the amount of information shown in the thumbnail? For example, If I put an image at the top of a note it fills the thumbnail and looks amazing, then when I add more images or text then the thumbnail updates to show more in the thumbnail, which looks less amazing. Is there a control character, some markup language or the like, that I can use to say, "stop thumbnailing from here"? Then I could control what is shown in the thumbnail and make fabulous looking and easy to navigate notebooks. Apologies, if this is an obvious answer, I had did quite a bit of searching and but could only find people saying that the thumbnail is automatically created. Thanks in advance.
