I am playing with the Quick Add Bookmarklet... it is a great feature, but to me it's missing a HUGE function. When you tag something with Quick Add, it should take the URL of the current page and stick it in the URL field of the task. This way I know what page the task relates to, and I can get back to it later without having to search or use a separate bookmark.

If there's already a way to do this, please let me know.
