@tomquirk I made a couple small css changes here. Do you mind reviewing and merging to your branch? I like the pop of $purple on the incoming drop. Makes it a bit more exciting. Eventually, I'd like to add some kind of svg animation on hover there. I also added a border-radius to the dropzones, as I didn't notice one. If it looks good, feel free to merge!
