Skins in MediaPortal are much more than just themes. In fact, some skins include a variety of themes to suit your taste.
Skins can change the whole look and feel of MediaPortal, sometimes even the way you navigate, the appearance of menus, etc.
OK you found a skin you love, and you would like to change just a few little things! Can you? Sure!
Skins are created using simple xml files which can be edited in any text editor like Notepad.
The only problem is that some things are easy to change and some are considerably more complex.
