I have a php site setup with multiple controllers for the different sections of the site.
e.g index.php, gallery.php, faq.php etc.
Currently I have a base template which I call from each controller, which in turn includes the relevant content for the page. I also use tinymce to edit this content file.
So it's really a very simple cms.
Edit: To clarify, I have several new features I would like for my cms. e.g Specific section editing, menu editing and a few others.
But I thought instead of continuing development on this and reinventing the wheel, I'd try to find a cms which can plug in to my multi-controller system, instead of forcing me to develop my app in it's framework. I guess I want it to manage just the content, not any other backend stuff of my site.
Hope this is understandable.
