Module support?

It's not difficult to understand at all. But WireDesignz' HMVC library does something a little different. It's not necessarily dangerous, but can be at times. The get_instance() command is built into the CI_Controller, and represents an instance of the current controller, as you said. However, when you load a second controller you now have a conflicting instance that is pointing to the second controller whenever accessing something not specifically set in that controller. To get around this, the HMVC libraries, IIRC, have an additional CI class that is used to help create a common instance that $this points to for things not within the class. And this seems to work most of the time, but can lead to some tricky debugging moments.

I want to use MVC triads as visual widgets that I can simply put within the views wherever I want. Actually, it is often a designer to do these visual changes within the views only, without touching controllers, libraries or other programmer's stuff.

And that's a design choice that works for you, and that's awesome. And a decent use of MVC. What I was proposing was simply replacing the C in your triad with an L. Conceptually, they're very close, but controllers in CI have a very specific design that I think runs risks and makes things more difficult to debug on occasion. (See the Form Validation library issues that HMVC system has). Instead, the Library represents more of an Entity, I guess, than a controller, since it's not responsible for controlling the flow of data from request to response.

You're right - and I said there I liked what they did. I even implemented a simplified version of it. However, that wasn't controller calling controller. It was calling a separate class, which, in the CI world, is a library. And I don't believe their controllers have the same "global $this" issue that CI does.
