Nice service, but entering in text into some of the fields can result in wonky formatting if more text than can be displayed is entered. And it's not easy to re-visit the fields and edit/shorten the text.
Mike O
Wish there was a way to make all fields NOT-required, and add the required feature to the one I want, rather than undoing. Also, wish there was a way for the app to add fields where they seem to belong.
