PiazzA Theme is for the new CM Theme Engine introduced in CM11.
You will need to have a custom Rom that supports the CM11 TE installed on your phone or tablet.
CM11, PA4+, and AOKP are some examples of the custom Roms.
The main focus of PiazzA is to get square. ;)
A lot of icons have been Piazza'd. Over 1200+ and more to come.
What has been themed in Styles so far?
Android Downloads / DocumentsUI
Android / Google Keyboard
Android / Google Calendar
Android / Google Email
ES File Explorer
People / Phone
This theme will grow in icon support.
But to do that, I'll need your help.
Please goto the PiazzA Theme Community on Google+ if you have an icon not Piazza'd.
Thank you for your support and I hope you enjoy PiazzA.
Added Dirty Unicorn Settings icons.
Added more consistency of system icons.
And of course added more app launcher icons.
