First time I installed the MIUI rom, I was confused as to where the app drawer was. Only after reading up later on I realised this is based on the iPhone's layout. Having used it for some time now, I don't seem to mind it. It does feel fast
so basically these theme put all the icons on the homescreen itself like the iphone?
Yes, and if someone still wants the 'feel' of an app drawer, they can create a folder on any of the home screens and put all apps under that. However, having used this one I don't see any additional benefit for that one extra click.
