I would love a way to change the color of the note previews, whether they're shown as cards, snippets, list, etc. A way to "highlight" the preview in different colors would be great. I tend to use different notes for different projects and it would be helpful to see which notes are a priority or which project list is complete at a glance. Something like being able to set all educational notes to have their previews highlighted green, or all the notes that need attention can be highlighted red would be super useful. Something like that.
