We just added 2 popular feature requests on our Web Interface: Time Tracking and Grouping Tasks by Projects
For each task, you can set a number of hours associated to it.
If you have set hours associated to at least one task in a given project, you will see a new Time Tracking section in the Project View page.
It shows the total number of hours for this project and the list of corresponding tasks with the person associated to it and the date.
Also in the My Projects and All Projects tab, the total number of hours of each project is displayed, giving you a quick glance of how much time you spent on each project
Grouping Tasks by Projects
We also added a new group by option in the My Tasks and All Tasks tabs : Group by Project.
You can use this convenient new view to quickly browse tasks by project and see the number of tasks for each project in just one page.
