Nice app, but it is at it best at an iPad... The buttons are a bit to small... I tab wrong sometimes... I saved one time, insted of loading, and lost my entire project on which I was working for Day's! You can simply solve this by putting an announcement like: "Are you sure you want to save?" And make the Element-Menu possible to swipe, so you can make the buttons bigger at the iPhone version (you can make an iPad and an iPhone version of your app, for if you did not know.)
Yours sincerely,
A dutch guy, who loves PowderGame!
P.S. This app was a hard work, am I right? A big tank you then!
