Needs some updating, but pretty good

The release of Sierra makes it load twice in the toolbar, where one of the instances glitches to a white box every now and then. Further, should blur the background of the black box to match rest of the UI of macOS to make it more seamless.

Could also use configuration for multiple displays.

Otherwise, this program is wonderful, and I use it several times a day.
