The Groups view displays overlay layers in nested groups.  

Layer View  - This button toggles between Layer View described on this page, and Group View.

To move a layer into (or out of) a group, simply drag and drop the layer into the relevant group folder.  Alternatively use the "Move Items" tool described below.

Move Items - Select one or more layers using the left mouse button along with the control or shift keys. Click the Move Items button. Finally, click on the layer to move items into.

Load Template - This option restores the overlay groups from a template file.  The groups loaded from this file will overwrite.
