Detailed mapping system!

Wouldn't it be great to look down on your map and actually know what you're looking at? Now, Im personally a Minecrfat PE player, and I think PC players have the huge luxury of being able to put down named banners and seeing them in the map. For example, if I were to name a banner "home" and placed it at the entrance of my base, I would then be able to see "home" on my map and differentiate the little blocky colors. Now you would know exactly the difference between those two brown smudges! Its a great system, but unavailable on PE. Mojang has been working to reduce the differences between minecraft on its different platforms and I think that this would be a great addition to that work.
