Make it cleaner, simpler!
All I need is a simple list that sorts alphabetically and can be synced across. Is that too much to ask? Get rid of all those sub crap, remnder, and starred, that's why we have calendars. Calendars and list serve different purposes read David Allen's GTD and you'll know what I mean. My point beign, your app tries to do too much and it's plain cluttered imo. And allow to put white background instead those ugly defaults.
