Page Field Size
Certain fields just don't display all that well when you select average for the page field settings in application designer. For such fields, consider using maximum to cater for the fact that there might be data that will be cut off otherwise.
An example where this was not done is the Run control ID field in the Schedule Jobset Items page:
This turns out to be a real pain because if you have a long run control ID as you can't be quite sure exactly what value was entered into that field!
