Plain copy paste from old forums.
Some ideas Kmc asked me to get written down.
Stepladder: Bulky, click on an open space to place the ladder. Giving you a way to navigate up and down a z-level. Use in hand whilst standing beneath open space, to place the ladder simmilarily. Large in hand sprite beneath arm.
Compact ladder: Syndie item, dark and red like the angsty teen syndies are. Foldable loony toons style so it can fit in your backpack. Works the same as stepladder.
Engineering scanner goggles: Gives them another mode on their multi use goggles. This mode marks all tiles around you that has openspace above the tile, around you.
IC action: Look up. You have a short action bar pop up apove you as you “look around”, marking all tiles in view distance for a short while, where there is open space above you.
