The Project Browser / Navigator is always visible in TextGridLab. It provides you with easy access to and administrative functionality for all the material related to your project(s). The Navigator serves as the starting point for using the TextGridLab.

The Navigator is used for browsing the objects of the projects in which you have been assigned the role(s) of Observer, Editor, Project Leader and/or Administrator. All of your projects, aggregations and further TextGrid objects are displayed in a tree view. You can use drag-and-drop functionality and the context menu to manage the elements.
