A new enchantment called, "Anti-Gravity" (or 'Flight', whichever anyone agrees with).
It comes with ranks. (I,II,III).
Okay, so we need statistics, and I have a solution.
Normal bow:
24 blocks straight, flat area.
Gravity I: (Six block increase of range)
30 blocks straight, flat area.
Gravity II: (Another six blocks)
36 blocks straight, flat area.
Gravity III: (Range doubled altogether.)
48 blocks straight, flat area

A. Make it so that it's 1/2 the strength of leather.
or...
B. Incorporate it with leather armor, so that it acts like an additional layer of armor.
What I mean by that is:
Say you have a whole set of leather armor. That's a done deal. You make a plate of wood armor, to go over that leather armor. That'll make it reasonably strong. So. About 2/3 the strength of iron armor, and that's that.

You get enough Twist Powder for about 10 blocks. What do you do with it? Toss the stuff at a block by RIGHTCLICKING and you have a block that does not defy gravity anymore! But here's a special property of it, if it is touching an edge of a block, it will lock there. That means you can make hills fall into nice staircases. You can also pull the blocks. Just right click and hold it. You can pull it out a space.
I believe this would be an interesting addition. The End could be completely like this and you can escape out of this. While the Endermen take away the blocks below you. This could add a whole new way to play. And yes, I have been playing Catherine lately.
