This is cool! I ran across an issue when trying to make an entry for Email that uses mailto: the subject is URL-encoded (in this case, the issue was that spaces were pluses). I had the subject as the subject of the email, making it clumsy to read.
Now of course, this was before I saw the email choice at the top, making the need non-existent. Since a URL is expected, you could have a file:// based one, where spaces are ok, so if you could make URL-encoded optional, that would be awesome. Perhaps another attribute of the fdsendto element?
