SUMMARY Selecting Unread and Total in the folder list gives a display where the Total field width can only be expanded - Never shrinked. Any attempt to shrink will just bounce the marker back STEPS TO REPRODUCE 1. Set up kmail with folder list (and in my case favourites) to the left. 2. Right click on the folder list header and select "unread" and "Total" 3. Expand the Total field slightly. 4. Try to shrink it back and watch kmail refusing to do that OBSERVED RESULT Cannot shrink the last "Total" field in the list EXPECTED RESULT Normal shrink by dragging separator should be possible SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Mageia 7 (available in About System) KDE Plasma Version: 5.15.4 KDE Frameworks Version: KDE Frameworks 5.57.0 Qt Version: Qt 5.12.2 ADDITIONAL INFORMATION Couldn't find a place for reporting kmail bugs. Putting it under PIM in hope of someone finding the right place for the report.
