Saw mill block

Here's an idea, What if a saw mill block existed? I think that a saw mill block would add a easier way to get certain blocks. It would allow people to get certain wood blocks such as stairs, slabs and a new way to add different themed ladders without sacrificing the need to add new sticks. Give a saw mill block to a villager and you get a lumber villager which would trade emeralds for sapplings, bonemeal and different wood blocks. Alternative trades could include flowers, charcoal iron tools for mid game play. It's a small feature but it would be a good one. Thank you for reading Cole_TSM
