I like this version. Except for 2 things.

The screen to the left of home screen is gone, I'm so used to it and liked it a lot and there's no way to add a screen to the left of the home screen as far as I know.

And the app manager screen (one you swipe up from the bottom). It looks nice, flashy and all that but it doesn't seem to be very efficient in showing what apps I have running.

Is there any way I can make it better? Or should I just downgrade back to 4 or just get used to it?
