Some kind of Pulley system elevator that you can set at least a wood stem pile on or any crafted item that size. That would be awesome! It would really go well with base towers and look so much better than a bunch of trampolines. 

Definitely feel this would be a great addition

I want this so much, would definitely help with going up the 35 bounce web tower I have made for quick travel anywhere in the backyard. Maybe also something like this for the ziplines too, for easy transport of a lot of grass planks and weed stem.
