Here's another suggestion for notes... one that is probably more trouble than its worth (I really hate programming graphics myself).
Being able to link two notes into a vector so that we can bookmark paths.
For example I used to have a huge series of bookmarks that I made by flying above the Fel Reaver in Hellfire Peninsula which basically mapped-out its path in a series of purple diamonds. Being able to string those together into a connected set of vectors, would have been excellent (not that it would have provided much extra functionality). I probably would have also created paths on either side of the main to indicate aggro radius and thus explicitly define a "where you have to keep looking over your shoulder" zone.
I'd probably also use it for marking the trails on Mts Neverest and Kota and the back-way into Tian monastery.
