Edgeless v2

Edgeless v2 adds multi monitor support, although this is limited to 2 monitors.  Also added the option to have wrap on all sides, just horizontal or just vertical.

ssOverlay

Similar to Dark Screen, ssOverlay (the ss stands for Scotopic Sensitivity) places a coloured overlay on the screen.  The colour and transparency levels are adjustable, the app is multi monitor capable and can either be installed to the hard drive or used on a pendrive.
