How did Coach manage to make his ' Now playing' and 'Art & Details' look and position the the way they on the screenshot?
On each of these panels do you see where is says "Art and Details" and "Now Playing"? Those are the Title Bars and they must be visible if you want to move them. If they aren't visible, right click somewhere within each of these and look for "Show Title Bar" (for the Now Playing you may get a big menu window, go to View and click Show Title Bar from there). Once these are visible you can move them around.
After installing the skin it positions itself in the left down corner and doesn't let it to be moved.
The player moves by clicking and dragging. Some players are difficult to find the right spot, but keep trying.
I installed the skin without any problem as well as Monkeyrok and the Lyrics Viewer. Question remains : in which folder/location do I leave the contents or file folders of: Monkeyrok and Lyrics viewer so they have the same skin.
The skins should automatically install to their respective folders under the Scripts folder. If you want to change skins you click Tools>Options>MonkeyRok or LyricsViewer and change the skin.
There should be a float player which can be opened and closed just by dragging a sort of handle. No matter what I do, there's nothing to drag and I see no 'handle'.
In order to view the float player click the minimize box in the upper right of the skin. The float player shows and the handle to move it is the two arrows in the middle of the right side.
Hope that helps.
