Control Center for Mac not only works fine in OSX Yosemite Developer Preview, but actually looks better thanks to improved blur mechanics.
The blur effect can now be increased much higher, making the text and controls much more distinguishable from the background. And it just looks gorgeous.
There were several rumors that Apple would release a Control Center feature in OSX Yosemite, but that turned out to be inaccurate. This gives new wind to my development of Control Center for Mac, and I have some great ideas for taking this app to the next level.
