No one mentioned this so here...
To change the meters in Sys, you only have to right click a loaded skin and choose edit configuration. You can edit everything but the graphic files themselves.
If you want the skin 50% smaller you'll need to use a graphics program to modify all the graphics by 50% then re-save them to the same skin directory.
Then you can scoot them around till they fit right by using 'edit configuration'.
