Things to know:
- This is the 4.4 Launcher, but it is not the GEL. There is no Google Now integration at all. (and the long-press Settings icon does nothing)
- The Quick Search Bar will not display after you switch to Landscape. Pressing Home while in Landscape makes it pop up.
UPDATE: The apk linked below is more current than the one attached. It's built with no minSdk restriction and should work on 4.2 or above. (It definitely needs 4.2)
