Single Window Menu screen in Nexus 5 I am using Nexus 5 with Android 4.4.2. Its menu screen contains "3 screens" to accommodate all the apps I have. But I remember in older Android (I think I saw it in Galaxy S phone) that all the apps were put in single screen and we could scroll down to get any app.

So I want to change this "multi-window" menu screen to a single scrollable window.

Is it possible in KitKat? if so, how?
Currently on the nexus-5 stock launcher the 'Google Experience Launcher' or 'GEL' for short, there is no way to customise the app picker / app drawer. You could install a free third party launcher such as Nova Launcher which I have checked and it has a 'List' option, or Apex Launcher 

The potential downside to a third party launcher is you will lose the Google Now integration on the left most homescreen and the Ok google functionality.
