Review request for Plasma, KDE Usability and Vishesh Handa.


Bugs: 275645?
    https://bugs.kde.org/show_bug.cgi?id=275645?


Repository: plasma-desktop


Description
-------

This adds a "Clear history" button to the plasmasearch kcm to clear the history.


Diffs
-----

  kcms/runners/kcm.cpp 10b7683 

Diff: https://git.reviewboard.kde.org/r/123889/diff/


Testing
-------

Clicked button, history gone, popup updated automatically. Could perhaps check whether the history is currently empty and be disabled in that case? Dunno if adding a file watcher to track live changes is worth it though.
