It'd be nice to have the hotzone for a particular button change to be area covered by the _over layer. This would allow for drawers to be displayed on mouse overs, rather than clicks.

that´s already possible. It just depends on the design of your button_normal and _over state. You can design the over state as big as you want, for example showing a drawer. The only rule is that the area of button_normal doesn´t have to be empty in the _over layer. If you want a bigger invisible hotzone you can do that by setting the layer transparency to 1% (even 0% works).
