Views
The View menu controls many of the features as to how the Gantt chart window appears while you're using it.
You may toggle (check / uncheck) features in this menu with your mouse.
Useful Tip: Hiding the Gantt Chart pane turns JCVGantt into a text-only outliner. This is useful for rearranging topics in MindManager and viewing more items than can easily fit in the graphical view.

Here's a summary of what each of the view menu checkable items are for:
graphic
Tasks
Shows the Gantt Chart Window and/or Tree Pane
Resources
Shows the Resources Window
Zoom in
Zoom in on the Gantt Chart Window. This changes the timeline, resulting in a narrower section of time.
Zoom out
Zoom out on the gantt chart. This changes the timeline and shows a broader section of time
Autocorrect Task Dates
When checked, task dependencies are calculated everytime you move a task so that dependent items "slide in time" automatically if you edit a predecessor.

This can get slow on large Gantt charts, particularly when running with Mindmanager... so you may optionally turn it off.
Match Task Colors
When checked, any color changes made in MindManager affect Gantt and vice versa.
