Duplicate object type, view object types as spreadsheet

I find object types useful as a database of characters and items. In this case, many types will have identical or at least similar fields. I have two suggestions for the object types editor to make these types easier to manage.

Duplicate the highlighted object type: Easier way to create new character or item types. As far as I know, I can only do this with a text editor.

Object type spreadsheet: View and edit all types as one big table of properties, either type-major or property-major at the user’s preference.
