Sadly, the new GUI destroys the designs of paks, and currently it's not possible to deliver a theme with the pak. I hope this changes soon.
Anyway, for those who care enough to change Theme for a pak, I provide Themes looking similar to the skin pak192.comic used.
This is probably not final, but for pak 192.comic, it looks neater then the standard skin.

Thanks, It's a beautiful theme. If someone wants to default this theme just rename the tab file to themes.tab.
