Installs perfectly, great work! (Nice touch with the configurable colors, too)

Want to upload it to the addons site so folks can find it when looking for skins? (https://www.mediamonkey.com/addon_system/admin/?category_id=38)

Better?

Great work!
FYI, the zip file you gave is not in the correct format. With the zip file that was provided, users will have to extract the folder manually to the correct location. For a drop-in installation, the contents of the addon have to be in the root of the archive, not inside a sub-folder. (If you want an easy command-line tool to automatically pack an MMIP of the correct format, try [url=https://www.npmjs.com/package/pack-mmip]pack-mmip[/url] ;) )

For the TV in the living room as a monitor I had once made a [url=http://sproetze.com/assets/Apps/Material_Design-GU.mmip] skin with large font in the player[/url] based on Material.
[b]ONE[/b] of hundreds possible colour combinations

As a gimmick you can choose the colour of 3 items and adjust the font size in 3 steps.
The space-consuming "My Rating" was banned from the player, because that is still displayed in 3 places, and [b]MY[/b] rating is not so important in the living room for the other family members or visitors.
The script from the mini player is used to prevent an overflow in the Player-Title.
Maybe someone else has fun with it?
