Add these 3 features and it will be awesome....
1. Add an option to remove the search bar on home screen , not everyone need a search bar.

2. Make it possible that the user can use the hidden apps without unhiding them. As of now it's a major hassle.

3. Add a locking feature so that we can lock the apps also.

If you add these features it will make it brilliant without making it very large in size.
