I'm looking for an application which will allow me to pin any arbitrary window running in Desktop mode in Windows 8.1 to the top, meaning it'll always be above the window I'm actively using.
Similar functionality exists in some video playing applications under the name "Always On Top". If I was on my Mac I'd use the program Afloat which not only lets me pin but force semi-transparency onto any window, which would be neat if the Windows application did too but is not required.
Preferably, the application would be a mostly-hidden one running in the task bar which would set up a keyboard shortcut for me to hit when interacting with a window to keep it always on top.
