How could I force mergetool GUI (KDiff3) to be always shown?

Question

How could I force the mergetool GUI to be always shown and disable any automatic resolving?

Sometimes when there is a conflict during a merge and I use the mergetool

Answer 1

If the problem strictly relates to unwanted conflict auto-resolution...

Once KDiff3 has opened, you could just press a Merge / Set Deltas to Conflicts from the menu, and the state gets updated to a beautiful, man-driven conflict resolution problem.
