New Shop Layout, In Progress

I have finally put together a plan on how I want the shop to work. A pic of the layout is below. The items that are in yellow are still in the building stage or not yet purchased, but adding them now seemed like a good thing to do. It won't be the last reorganization for me, a shop is never finished right? In the future I will be hanging a couple of clear shower curtains to enclose the turning area, in the bottom left corner, to keep the fine curlies contained. That should also allow me to use a small heater to keep things warmer during the colder months. Anyone have any ideas on how to tweak the layout to improve it?
