It's long bothered me that when you use stairs to make roofs in wintery climates, the flat bits of the roofs will gather snow, but the stairs don't. 1 snow layer is almost identical to a carpet, so shouldn't be much of a stretch for this mod to add.

I have no plans to rework how Minecraft snowfall or snow generation works at the moment. Note now layers have the additional difficulty of being able to stack up to 8 layers, which raises the question of if further layers stacked on top should also be depressed.

there's already a mod for this!

no neeed for it to be added here!
