I know the mapping is much better than Morrowind's, but I still get turned around and backtrace if I'm not popping my map open all the time.

Morrowind had a chalk module with LOTS of options. Would it be possible to port it? The chalk itself should be easy, just use the soulstone nif and recolor it.

Or, if the marks are too much, would it be possible to modify one of the blood "medallions" (or the ghost-sigils in the Anvil house quest), to be orange or bright green and permanent and placeable by spell or dropping? So I can mark where I've been without dropping a trail of clutter, for those times when I'm not leaving a trail of bodies behind me...
