Feature-centric understanding of source code is essential during software evolution. However, such understanding is difficult to achieve due to the lack of correspondence between functional features and structural units of object-oriented programs. In this short demo, we present a tool called Featureous that aims at bridging this gap. Featureous allows a programmer to easily establish feature-code traceability links and to analyze their characteristics using a number of visualizations. Featureous is an extension to the NetBeans IDE, and can itself be extended by third-party plugins. More about the tool at: featureous.org
