For me the things I would have liked to see were the ones below that I couldn't find and ended up drafting or re-grading myself -
- pullover sleeveless hoody (didn't want to attempt a zip in knit!)
- footed long sleeve all in one without a centre back seam in larger size (3 approx)
- larger size (again 3 plus) bodysuits (long and short sleeve)
- bodysuits without a neck fastening or being envelope style (although a recent ottobre covered this one off)
- leggings (think you've done this though..

)
- waterproof trousers with enough room for cloth nappy butt
On my list to make that I haven't yet found a pattern for
- waterproof overalls
- hooded poncho
- wet weather jacket with a decent adjustable hood
