Signs would be nice.

[Freth]

It would be great if you could make custom signs in-game to display important information. Is it in the works?

[BetaSnake]

I hope so. Use paper to make notes for people to read.

I rather them make other things before the signs. Something more useful like a compass or even something amazing like diseases and medicines.

they are probably not in the works but are planned.
