I voted for it, Morrowind style, but it would not be a necessity for me. It would be useful as a way to navigate without quest markers, though.

Optional, with transparency slide, and it'd be fine. So I voted "yes, but with this change..." The change being, the option for it is there, but standard gameplay would not rely on it.

I wouldn't plan on using it. I don't want things cluttering the screen. It'd still be neat to have the option.

If you could turn it off.

Nope, the less HUD the better.
