YES! This would be so helpful. I use Evernote as a database to keep track of my sewing patterns. Each note has a image of the front of the pattern (completed item picture), and the back of the pattern (words/numbers). When the back of the pattern ends up as the thumbnail, it's pretty useless as a way to quickly browse through to see what I have. Hopefully that explanation made sense. It would be a lot easier to just pick which picture to have as a thumbnail than to have to manually go and resize images.
