Dark Silver - Radon 1.0.6.
I can confirm.

I really like the look and feel of the Radon 1.0.6 "Dark-Silver" skin on MM5 Gold. It looks great, but I am having a minor functionality issue:

There is no "Visualization" menu item under View or Play in the Main Menu, or in the menu of the Preview window. It's not "grayed-out", it is just not there.

When I install other skins, the Visualization menu item is present again.

Not to worry! I had already messaged Radon about it and it looks like he's uploaded an MMIP version now. So if you go back to the page and hit download, you'll get an installer for the skin.

For future reference, if a skin is provided in .zip format, you can copy the zip to the Skins subfolder in your MediaMonkey install directory (e.g. C:/MediaMonkey 5/Skins). (Or you can just rename the .zip file extension to .mmip)

Anyone know how to install the Radon / Darksilver skin? All of the others have mmip extensions that can be opened by MM5, but this one has multiple files and subdirectories and no apparent way to actually install?
