Not exactly sure how it would work, but I would like to be able to make custom buttons.

It's planned, but I don't know when I will get to it.

FYI, SimpleLogic's Wires work perfectly fine with LittleTiles, including even being blocked (no redstone connection) on sides that have LT blocks blocking the path.
Meaning, adding redstone wire stuff probably shouldn't be a high priority, since if you want to hide wire, you could just put it a block under or in a wall and cover it up with LT's blocks.

We shall see.

@CreativeMD to add to this, maybe even redstone-wire like stuff, that would replace many many mods, though im not sure how difficult it would be..

I will start to work on it soon.
