The Inspector is the upper section of the Object Sidebar.
Use the Inspector to edit objects.
The Inspector will change to reflect the object or objects that are currently selected. This inspector panel is different for each kind of object and offers options and setting specific to that object.
With tables, fields, comments, canvas areas and views, SQLEditor allows you to edit multiple objects at once. Note that you cannot rename groups of objects and that some types of objects don't allow multiple editing.
