Custom page addition matching current layout and format

[letis009]

Basic Infos

Awesome library guys. really is a lifesaver.
Feature request maybe or just missing instructions.
We looking to use CSS format set in Main and PARAMS,
going to /custom presents a blank page with text, is there a method to use all the styles and scripts from index and params ?

I have already added backgrounds and icons to styling but do I need to duplicate the entire page in code again ?
