For those looking for things like transparent nav and status bars (see my pic below), but don't have 4.4 yet, then you may want to head over to Google+ and follow the Nova Launcher Beta community. It is the only way you can get the Beta update. (You also need to join the community via a desktop browser, not a mobile browser. This is key to be able to "opt in" to the beta program. Once you opt in, you will be able to go to the play store and see the Nova Launcher 'update' button.
