Today, I need a free tool to manage my projects. I like a tool like Microsoft Project which I have ever used in Windows. And I am happy to say that planner is a general purpose project management tool that provides a variety of features, which are available via 4 separate screen layouts called views (Task view, Gantt view, Resource view, and Resource Usage view). This tool is distributed under the terms of the GNU General Public license. It is available to install in Ubuntu Feisty.

sudo apt-get install planner
