The ability to have more than one account on one device without constantly logging in and out. If you have two kids and they are both using isoccer the current interface is a major pain.
ISoccer has to rebuild app to allow for multiple users, otherwise those of us with more than one kid, which is a lot of us, simply can't use this app. Please fix ASAP. This is the single reason we don't regularly use iSoccer and exactly why we don't subscribe. Fix the and you'll have a double subscription from me!
