Baby got gauge?

I really like this app. I own a knitting store & I used the old-skool paper version for 9 years before I got an iGadget, and I also use Ann Budds books for reference too. The only thing the app needs are the in-between gauges: 3.5, 4.5, 5.5, 6.5 sts/inch. So many standardized yarn sizes fall in the middle gauge, and I still have to use a calculator to figure out the final yardage. Please fix!
