In the drawer you see only the system and your installed apps, not the shortcuts! Was always like this. To use shortcuts you need to long press on HOME screen and select "shortcuts". Now I don't know if the drag-drop dock function works on Android to put a shortcut there, but you can select battery apps (like "Battery HD") , so when click on the app/dock shortcut you will see the battery stats.

Make some tests using the dock widget from the link that I wrote here (in my prev post).
..and yes, XWidget is in development so pls wait for more options and features.
