I think Occasions & Seasonals should be rescued from "Whatevers Left," and made into a new category. The various occasions--Xmas, B'day, Easter, etc.--would then be the subcategories of O&S.
Personally, I'm just bloody tired of having to un-tick that stupid "private auction" square every time I post something seasonal.
You might also consider subdividing Xmas into Lighted Decorations, Non-Lighted Decorations, and Lighting Sets.
