I recently launched WatTools. This is a site for University of Waterloo students to find useful tools for school. Most of these tools are built by other students and provide functionality which is missing in Waterloo's web applications.
There are tools for selecting courses, being notified of interviews, putting together a list of citations, and more!
In other news, I updated and moved Quest Schedule Exporter to http://schedule.wattools.com/
In case anyone saw my previous post I'd like to say that I've completely changed my mind about what to do because the interview notifier exists already and the schedule exporter is good enough right now. I will continue to expand WatTools and try to see if I can get Waterloo power users engaged in sharing their tools.
