The tasks in a project can have very different durations and
sometimes you need to have a close view of the time line to see the
details of some task dependencies, but other times you need a higher
level view of the whole project.
To support both needs,  has a powerful zoom system that
lets you zoom to fit the complete project, zoom in the view or
zoom out incrementally to whatever size you like (hours being the
lower limit, and years is the upper limit).
Zoom to fit shows the entire project duration
in the Gantt view.
You can use the Zoom in and
Zoom out icons to select the length of
time line in which you want to work.  When the view is
zoomed to a detailed level, nonworking hours are shown for each day
in addition to weekends.
