Mod description

Cycle Paintings is a minimalistic mod which allows players to cycle through placed paintings by right-clicking them with another painting in their right hand. Also works with modded paintings.

Why would you like the mod added?
It's a good and small QoL mod. :)

Sure thing, now that it's open source :)
