Hi Eduardo:
I really think that you are confused in saying that Hyperbole and Org are hacker-unfriendly. Yes, they are targeted at users who don't have to understand the programming, but if you do understand Lisp programming well, the interactive features are available as Lisp functions in almost all cases, so you simply have to dive in, find the functions you want and utilize or change them.
In fact, Hyperbole offers 'action implicit buttons' that utilize angle-bracket syntax to turn any Lisp function (or hyperbole button type call or variable reference) into a hyperbutton that runs the function with arguments or displays the variable, e.g. <find-file "~/.org/
my-org-file.org">.
With Hyperbole, much of the behavior is factored into class-like libraries with the 'methods' alphabetized and separated into public and private groupings. Now some of this code is complex in order to handle many contexts and make things simple to the user but that is a matter of you understanding this complexity if you want to hack on it.
I'm not sure what else you could ask for in packages.
