This is a great app of high quality. A must for bloggers who are on the go and need to create posts from their iPhone Or iPad. The UI is fairly straight forward and intuitive.
The only other thing I can think of that would be useful would be Dropbox integration. I would love to be able to select a folder in my Dropbox as part of the preset options. This would be a big plus for bloggers to keep their images sorted—especially now more and more platforms are starting to integrate with the service.
Oh, and file naming!
