Microsoft beta testing its Arrow Launcher for Android; download the APK now19
A swipe to the right takes you to the Notes & Reminders page where you can type in a list of things to do and check a box once the task is completed. A swipe in the other direction brings you to a list of people from your contacts list that you recently got in touch with via phone, email or text. It also provides you with a list of frequently used contacts, as well. You can also swipe up to see more options including additional dock shortcuts. The app drawer is posted alphabetically, and you can use your finger to slide down a list of letters to reach an app faster.
Join the beta group by submitting a request to the Arrow Launcher Beta community on Google+ (click on the sourcelink), or you can download the APK. Remember that this is not yet a finished product. If you go the latter route, also remember to enable the unknown sources settings on your Android phone. The APK can be found here.
