Foren / Cotonti / General / "comment" in admin panel

on admin add this:

<iframe src="your/path/page.php?al=admincomments" style="border:0px;width:100%;height:200px;"></iframe>

admincomments is the page alias.

on your page you'll add this:

<style>
#the-element-to-hide, .the-class-to-hide, #and-so-on {display:none !IMPORTANT;}
</style>

the css hides your elements and should overwrite its standart values. remember to put that only on the page you actually want to use as the admin comments.
this maybe a dirty solution that works without any plugins but iam not sure about validation and browser compatibility, you also could use javascript or jquery to hide the elements...
