This launcher is ment to be as light is possible I think. If you press "menu" you can add folders. If you want to categorize your apps I recommend "Apps Organizer" from the market. If the everything would be includet to the launcher it will make it slower and less light weight. And this is not what FTL is meant to be (pls lowveld correct me if I'm wrong)
There are a number of widgets and apps to download which you can use for optimization, some examples?
Android Pro Widgets (I use for Facebook, Twitter, Calendar)
Apps Organizer (for folders, you can use folder organizer as well)
Scrollable ContactWidget BETA (for contacts)
This is my personal setup, but other people may not need it. So you have choice to include it to your android, but if you don't need it does not make it heavy
and keeps it a "faster than light"
