First of all I'd like to say how impressed I am with geany. I ran it and it went KAPOW!! I've been using emacs for the past 7 years. Every once in while i try to break away and use something more modern like anjuta or codeblocks but I always revert to emacs. I've been using geany for a week now. So far no emacs =)
Anyways I saw a request for code navigation and I wanted it myself so I hacked up back and forward buttons. Right now, it only changes the history when you go to a definition or declaration from the context menu, but I'm open to suggestions on this. Also, if the file is no longer open, it removes it from the queue and goes nowhere.
If anyone is interested I'd be willing to polish this off and submit it for entry into geany.
