Thanks to Jeff Bolding for bringing this to my attention. If you would like to display more than the standard 10 WorkUnits in your Inbasket you can Add a User Preference value (yes, you have to do this for each user).
You can use always create a flow to Query all of your Users and a WebRun to add this setting to each one:
Web Program: bpm/userPrefForm.do
Post String: method=Add&id=davidwil&systemName=INBASKET&fieldName=NBRWORKUNITS&description=Number of WorkUnits Displayed&fieldValue=20
