When attempting screenshots while using multiple monitors under Mac OS Mavericks, it blacks out all monitors but the one you’re on and brings everything from your primary monitor over to the monitor you’re trying to take the screenshot from. Can be worked around by dragging stuff you want to screenshot onto your primary monitor and screenshotting it from there. Other than that, no complaints. It’s simple to use and exactly what I was hoping for. Would give 5 stars if the multiple-monitors issue (or lacking feature) gets fixed/implemented.
