Not sure if this fits with the area that Hafen is set in, but could we get hedges?
Working as a wall-tile, offers the same amount of protection that a stickfence would, so majorly just for decoration, but perhaps to destroy them you right click > chop instead of destroy.
I'd like to circle gardens or public areas with these things
Hedge gates would be cool too, but just a stickfence gate would work just fine
