Hi,
without 'Apply' the Overlay Options dialog determines the default
values, i.e., the properties of overlays created in the future.
With 'Apply' you can, in addition, also modify the currently existing
overlay(s) of an image.
If you want to modify the properties of one (existing) overlay, you can
also long-click in it to select it, then use Edit>Selection>Properties
(y shortcut), and deselect it (Edit>Selection>Select None, shift-A
shortcut).
