Per-Post CSS warning

It’s cool that it’s possible to do per-Post/Page css in the WP Post Editor.
However, if you do this, later you might not realize that you’ve done this.

Let’s say a year from now, you go back to your site that has some per-post CSS, but you don’t remember that. When you look at SimpleCSS’s MAIN css panel, you don’t see any CSS has been added to the site. So, you blindly turn off SimpleCSS, and you are unaware that you have per-post CSS. Bam! Those per-post CSS’s no longer work!

Could you add some feature to the MAIN css panel that would identify which posts have had SimpleCSS added on a per-post basis? That would be grand.
