Preferences: The Type section needs to be cleaned up. My suggestion:
(x)default only, ()user defined only, or ()Both
()or select only 1 type below [which is the current "use type" field]
[no matter what they select above, the type list always shows all of them.]
I have changed it following your suggestion. In this release I have also changed the type management inside. Now it works with a code instead of the description.
