That's true for code that adds functionality, but IMHO code that
improves usability (such as yours) should go into the core for two
reasons: one, it should be usable by everyone; two, it can take
advantage of core improvements without keeping backward compatibility.

This is just my opinion, though.  It's your code and you're free to
submit it to the GNU ELPA or any other archive :)  Just let us know what
you prefer soon so we can move on with it.

That sounds fine, especially if it can be implemented quickly. Otherwise
maybe we should adopt Tom's code now and improve it later. What do you
think? I'll hold off until you and Tom have given your opinions.

Either way, I am excited about this. It will definitely improve the UI
experience!
