Started working at implementing some 2D and 3D constraints in the application. Read all the documentation available. Will try at the beginning to implement some helper that allows the user to grab the end of a segment and modify it.
Applied at Rally and TargetProcess for evaluating their community editions of Agile software development. Looked also at the others from the market like Mingle, XPlanner, VersionOne, Agilefant. Looked even at MSF Agile. By the end of the week I am planning to adopt one of these and use it for the development process.
