Allow url's in annotations
These enable a jump to a Wikipedia article, a YouTube video clip and so on.
Refer Highlight implementation in Photosynth 2 Preview.
You can insert urls on your annotations, but it wont’ show any preview.

By the way, suggest consistency in wording. The tab is called 'annotations', but in the tab content 'note' is used.
