Users Appreciate

  • inline editing of the task name
  • quick access to tasks using a modal or a direct link
  • mouse-enabled canvas moving
  • visual representation of issue priorities is a priceless feature for precise planning
  • moving of project including all sub-projects & tasks

Using task relations & delays, you can precisely plan the essential time needed between two tasks and if necessary, you can export the Gantt chart to PNG, PDF Excel, or MS project.
Thanks to the "Move project" feature, you can actually change the start day of a project without changing all task dates separately. This is a one-of-a-kind feature never seen in Redmine before --> you can effortlessly change the project start date even if you don't use the Gantt chart on a regular basis.
