Revert to Saved State: Check to load the last state when opening PhotoStickies again.
Show Inspector: Check to show the Inspector by default.
Run as Menu Extra: Check to start PhotoStickies as a menu extra instead of as a full application. Menu extras only appear with an icon at the right hand side of the menu bar and without a dock icon. Use the contextual menu, shortcuts (same as in the invisible menu bar) or the Inspector to still access all features.
