Not a high priority for me, but it would be nice to be able to choose from a small list of colors to differentiate some of the folders in the side menu by category. And, that part of Dynalist could use a little more color and pizzazz.
+1. only a few days ago i added emojis to the ends of the folder names just so they would stick out a bit more compared to the document names. i would rather have something more subtle like a colour though
