We need a way to speed up exploring maps in full. Its boring.

Say you have a 1/16 size map and you want to explore that whole map to display it on your wall via. item frame. At first it's fun but and you COULD just use the elytra to speed it up but it can get tedious and boring for any Minecraft veterans. I would like to see an item that can help speed up or complete the process in record time.

1.)  I don't know what this item would look like but I think it would be used in a cartography table. Please comment on ideas of how it might look or be named. :)

Ex. 1a)  Place any one map (that isn't locked) into the first slot and this new item in the second, and congrats, it will make the map 100% complete or expand the discovery radius by a factor of 2 or 3.

Ex. 1b)  Craft the item with one of the ingredients being a compass to make a super compass. then use that like you would a usual compass, to make a super map [8 pieces of paper surrounding a super compass].

Ex. 1c)  Have the cartographer trade a super compass/map for some emeralds and/or find it in generated chests. 

Please comment on your ideas. I'd love to hear about them, and don't forget to let Mojang hear my voice if you agree.
