Side-effect HTML support?!

I've recently discovered to my surprise that embedding some simple HTML tags such as <B> into an action, actually works as expected at least in the "Next Action" list, providing a simple and elegant solution to the occasional need for action highlighting, without having to add some sort of clumsy rich text-like functionality (thus keeping SimpleGTD simple).

Would it be feasible to extend this convenient behavior to all the other lists?
