Confusing/Useless-indicators of (un)modified directory contents

SUMMARY
In both Debian Stable and Testing, kdiff3's directory/file listing has no way to visually distinguish between these directories with binary-equal files or those with changes, requiring the user (me) to expand and examine... every folder.

STEPS TO REPRODUCE
1. Duplicate entire project
2. Make changes to only a few files in some subdirs, and not others
3. Diff the projects

OBSERVED RESULT
No difference even one directory up to distinguish if the contents are binary-equal.

EXPECTED RESULT
There should be some indicator to tell if one must look into a folder to see files with changes.  These files have the same mod time too -- they're not just binary-equal.
