@red_zebra - you should have access to change the title of the thread yourself, click edit on the first post, then click more options. If you're having trouble contact me again and I will do it for you.
What you need to do is create a script in autohotkey, that will let you select a theme, then it will scan the \skins\titan\ folder and then copy + modify all the .xml into \skins\titan\themes\XXXX\ that way can easily install + update
