When writing a plugin and runnit it on init / directly the Kirby has not loaded all the template stuff, like $page.
Here is an issue:

A plugin I made which forced me to user server variables

In my template
Right now in my testing environment I have this to solve the problem.
<?php do_before_template( $page ); ?>
<!DOCTYPE html>
<html>
<head>
I don’t think the function do_before_template() should need to be in my template at all.
Hook solution
To be able to do things with $page but before the template has loaded it would require something like a hook. In WordPress this is solved like this:

I think Kirby perhaps can make it this good or better, especially a better and more general name for it, like “before_template” or something.
Thoughts?
