Feature rich!
I bought this app first for my iPhone, now use it on iPad. Lots of features, options, and very few negatives. I have noticed it does not display in other apps as "open in..". This would be the best feature, as I could then replace several other apps! Maybe coming in an update? I would even pay more to get that feature.... Hint hint. Then it would definitely rank a 5 star rating!
