|The Main Work Space is normally organized with the View Selector to the left and the data view to the right.
As usual you will also find the Menu bar and Tool bar at the top, and the Status bar at the bottom.
Since both the View selector and the Scripts docker are dockers they can be moved to different border, floated or hidden. To show a hidden docker, use the Settings->Dockers menu entry.
The View Selector enables you to select the data view you want to display from the currently listed views. Views are grouped into categories for easier retrieval: Editors, Views, Execution and Reports by default:
Views can also be moved within or across categories, or added to or removed from the View Selector.
The Schedule Selector enables you to select the schedule all the views (e.g. Gantt View) shall display values from. Tasks wich has not been scheduled in the selected schedule is not normally shown in any of the views. (They are shown in editors, of course.)
The status bar shows messages and progress information. Most notably is the currently selected schedule shown at the right of the status bar. Note that most of the views in the Views category display information dependent on the selected schedule, so if the project is not scheduled (Not Scheduled), most views will be empty.
