This is an application launcher (not home replacement).
You can start this by long pressing search key.
But Motorola Droid, Defy or Sharp IS01, seems cannot do this...
Also you can start this from notification bar, but this still incomplete (Galaxy Tab is ok, Nexus One is NG).
First, you should register your favorite applications.
You can categorise applications.
1.1.7 : Bug fix.
1.1.6 : Just modify.
1.1.5 : Add registered categories list to menu on long press app regist list, too.
1.1.4 : Add open market, open PC market and registered categories to menu on long press app list.
1.1.3 : At target app list, add sort mode by date, add display mode main activity only. Add launch, open market and open PC market to long press on list.
1.1.2 : Bug fix.
1.1.1 : Make distinguishable main activity and others. First time, it take a while to upgrade DB.
