[Xenon]

open your config.php

enter $debug=1;

then in your admin-cp you can add templates to the global set, so such templates are seen in every style under default, not longer custom.

be sure to take out debug=1 after you've done that, because its a security problem...

also remember: with every upgrade of your vb, all global templates are deletet and the new ones are created, so you have to add your custom templates manually after an upgrade again.
