In an organization, a single TeamCity server might be used to host CI for multiple project teams. Hence, there might be TeamCity projects that are not of any particular interest to a team member. Depending on the team structure and setup of TeamCity, even certain build configurations may not be of interest to all the users of a TeamCity server.
TeamCity provides the ability to hide the web interface, projects, and build configurations that may not be of interest to a particular user. Projects and build configurations can also be reordered as desired.
