Please give users control over which thumbnail image is seen for a note. It's a critical tool, especially for visual thinkers, in finding content. For instance, my initial use of Evernote was as a digital recipe box. When I scroll through my now large collection of recipes it's irritating that the Bon Appetit Smoky Carrot Dip recipe features a picture of Green Mountain Energy.
It reduces the efficiency of this tool to have to find work arounds for either saving a non-congruent image or searching for content more arduously. If I'm using it professionally to organize a production project, the thumbnail image becomes even more critical. I hope you will fix this urgent issue soon.
