I originally posted this under suggestions in the main forum, but I realized later it might be more of a "niche" idea, deserving of a plugin rather than main-game implementation. The tl;dr (you can view the original post for details) is that I would find it immensely useful to have a common interface for accessing objects' internal state, like that of furnaces, minecarts, chests, doors, as well as mob sensors. As far as I know, there isn't a mod this powerful - yet.
