(I'm including a bunch of little things here.  Hope that's not bad)

The "Suspend Debugging" checkbox in the "Add Breakpoint"/"New Breakpoint" dialog 
should be called just "Pause"

"Print Text" would be better as "Print"

In the Exception panel:
Remove the "(Enter full name of class..."  text at the top. and move the package and 
exception class name labels to be aligned with the "stop on" and condition labels.
Change "Stop on:" to "When:"
 
In the "Variable" panel:
Change this type of breakpoint to "Field" rather than "Variable", as it doesn't apply to any 
arbitrary variable.
Change "Stop On:" to "When:"
Change choices in combo box to "Variable Modified" and "Variable Accessed"

In Thread panel:
Change "Step breakpoint on" to "When:"
Change choices in combo box to "Thread Started" and "Thread Stopped"

In the class panel:
Remove the "Class filter..." label and outdent other components
Change "breakpoint set on" to "when"
Change choices in combo box to "Class Prepared", "Class Unloaded" and "Class 
Prepared or Unloaded"
Change "Exclusion filter" to "Only Classes That Do Not Match This Name"
It would be nice to add a line of text at the bottom of the settings area which said "You 
may use '*' for Class or Package name"
