Sideline

Sideline is an Adobe AIR desktop application built with the Yahoo! User Interface Library. It allows users to create and group custom queries by topics of interest. Sideline is an open source application released under the BSD license. In addition to showing you which terms are trending on Twitter at the moment (more interesting and relevant than just watching the public stream go by), Sideline lets you create searches that get their own tabs in the interface. The first beta release is out and the code is hosted on github
