A second shower rod at the opposite side of the shower that holds shower necessities and bath toys. also, add another shower curtain rod directly behind the curtain for hanging bathing suits an wet towels.
I have a similar binder I LOVE and it helps keep my sanity and my household run smoothly I know where every document I need is and in an emergency I can just grab it instead of paying hundreds of dollars to replace vital documents and other items. I once figured it out and to replace our SS cards & birth certificates alone would cost me over $200!!!
