Stickies 2.6.0

Fixed a bug in the background changer which affected wide screen monitors and image scaling.... it now scales correctly.

* Extended the Show Desk ability to within actual Sticky notes. You can now double click middle button to hide all stickies except the one you clicked. Re show all stickes again but double clicking the middle mouse button. This is also accessible via a stickies context menu "Show Desktop, But Not This"
