I imagine that the addition of artwork to the folders was intended to be a "feature" but I would vastly prefer choosing my own art, if anything, myself. The current version doesn't seem to allow for deletion of all art to a blank folder, either. You might want to add some "blank" folder choices in a drop down menu or something, maybe even color them to enable organizing them to user choice to get around this inability to delete the art that Mezzmo has "chosen". It would be nice to arrange files by "Type".

In conjunction with this, It would also be nice to be able to add a folder for Source Files without having the sources intermixed with the Mezzmo defaults. I would like to be able to have all my "added locations" in one place.
