The More Difficulties mod changes some of the difficulty faces of the main levels, such as changing Dash from Insane to Tough. For these levels, the new difficulty face will appear above the vanilla one when this mod is installed.
Also, in my opinion the panels sometimes kind of blend in with the background right now (especially the thumbnails for the older main levels), so I'd suggest to maybe make them drop a shadow or to add a border around them for more contrast.
