Dwarf Fortress Expanded?
Allow me to introduce two wonderful external applications that improve fortress management and viewing.
Dwarf Therapist by chmod
A successor to Dwarf Foreman and Dwarf Manager, DT is an application that lets you quickly manage labour assignment, view skills, mood, create custom professions and more.
Visual Fortress by Baboonanza
My current favourite when it comes to 3d DF visualizers. Efficient and beautiful. You might also try 3Dwarf or Khazad.
