Please note that by default the Workflow tab, if it exists, will have initial focus when the entity editor is opened, otherwise it will be the first tab in the list. However, the tab which gets the initial focus can be controlled in the Administration area.
Qualify contains a number of built-in controls that can be added to any top level entity. Additionally, the user can create their own non-top level entities in the Admin area and then select these to appear as tabs for any other top level entity.
The saving of data within these tabs is controlled via the main entity Save buttons. In other words, creating or maintaining one of these child items will store the changes in memory until the main entity record is saved. If you close the main entity window without saving then any changes, for example new Comments, will be discarded.
