I personally like the design for the look and functionality. I can see it making it easier for people like me with back issues being able to tend and harvest better.
But, I would like to refer you to the original poster, retrohipmama,wordpress.com. She and I have exchanged several messages and she seems like a very nice lady. If you would like, just let her know that I referred you.
Thanks for your question. If you would, forward the reply back to me in case I have similar question in the future.
