Rather then spending time with suggesting and implementing new elements, wouldn't it be easier to put them in an external xml file or something that is easily editable without touching the source code? This way people could simply edit in the new elements they wanted to see, or change existing ones, and post these in a forum or something. Another powder game that I used to play (burning sand) had this, and a good portion of the game (atleast for me) was building new elements that interact with others in new ways that the basic ones did not.

And it goes without saying, bring back the old menu!
