The Action Launcher 3 has both a free version and a paid version that has no ads and has been a favorite of users of the Android platform. A stock Android feel and look is much appreciated, but it has other features that make it desirable as well.
Quicktheme is one such feature that determines, via the background, what the theme accents should be.
Quickpage is another that gives you a home screen which is hidden, but can also be accessed easily. Even with frequent updates, it has been stable and reliable.
