Need some help

Hey guys, I have been in a long search for the best audio front end player for an In-Car PC. I want a nice size display, and only some simple features available. I finally found Xion and started skinning last night. I have found that it gives me the functionality and interface customization that I was looking for, which I am very happy about. However, I have a few questions.
First, I'm trying to make the playlist display larger (about half of the screen), and increase the font size.
I have increased the font size, but the lines in the playlist must be defined somewhere else, because it cuts off the fonts. How to I increase the playlist line item size to be scalable larger font sizes?
Also, how to I make my skin windows re-sizable? I would like to be able to allow a user to re-size the main player and the playlist window. What about making the skin auto-scale to fullscreen?
Also, is there a way to launch an external program from a button? I would love to be able to make "quick buttons" to other programs that I use on the CarPC.
Thanks for the great player and awesome skinnability features. I think this is exactly what I needed. I look forward to your assistance.
