I absolutely love the Soul Tree Calculator tool that you guys created for Rift. It's extremely helpful and I know the vast majority of Rift players who frequent ZAM would agree. I do, however, have a suggestion that I think would improve the tool a great deal. A simple "Bookmark build" or "Subscribe to build" option (perhaps in the same area as the "Lock build" and "Link to this build" links are currently) would make managing your favorite builds and/or builds in progress, a lot easier. Although I'm fairly ignorant to specifics regarding the sites infrastructure, it doesn't seem that this would be too difficult to implement.
Any thoughts/feedback from the ZAM team or fellow Rift players?
