I kinda liked it, but it seemed to cause problems with Gmail and Google maps so I unistalled it pretty quickly.
The main reason I liked this and another similar program is the links shown in full in BB mail just clutter the email up and make it hard to read and time consuming to scroll through. If it showed something like "link" or "picture" instead of the entire link address, that'd be enough for me. As long as it was then possible to open or view one if desired.
