The latest update for iThoughts adds a URL import mechanism and a shortcut script for Safari on iOS. The shortcut sends the current page URL to iThoughts HD as a map element.
They have also tuned the selection and movement of map elements. Manipulating items feels very fluid and natural. Oh, and support for Emoji if that's your thing.
Is there any mind-mapping application on any platform as good as iThoughts HD on the iPad?
