It wouldn't have to make those things redundant. What they'd like, and what I'd like, is a little minimap that shows the roads around your position, so you can easily check if you're still traveling in the right direction. I'm not a big fan of having to open the full map every couple of minutes to check if I'm still on the right road, or if I missed my exit or something. For the rest, I'd want to use the compass bar, just a little help in navigating the world. As it is, I'm checking to see which roads to take to get to my destination. Then I see an explored landmark nearby and go "Screw it, I'll fast-travel there and make my way over." Having a mod for a little minimap to help with that will cut down my want for fast travel.
