One of the best features of Drafts for iOS is how it almost always opens to a blank document ready from me to type. This is a double edged sword though. Sometimes I come back from doing a web search and the document I was working on has been replaced with a blank screen. There's a Drafts action to solve this.
This is amazing. Like Gabe says, the feature that has Draft automatically open a new entry after x seconds is huge, but some times it gets in the way. This action helps.
