LOVING THIS!! Thank you!
This is exactly what I was planning on making after my exams finished!
A couple other things maybe for future releases (if you choose to):
-Buttons on launcher have a selection color when being pressed (like Espresso)
-More options for left/right buttons (such as changing it to messaging/e-mail/browser), just like basic apps obviously it would look odd if it was a random app's icon.
-Option to have only 2 screens
-5-column app drawer for portrait, and up to 7-columns for landscape view (if you were to include that in the future)
Again, I love it the way it is, just my 2 cents of a few more features that I personally think would make it perfect...
