Nice feature addition :)
Is there a plan for plugins to this plugin, so one could extend it with other checksum calculations? Not that serious here though ;)

Here some more quick more serious comments on the code:


src/widgets/kpropertiesdialog.cpp (line 2628)
<https://git.reviewboard.kde.org/r/128283/#comment65516>

    I propose to not cache the colors here, but instead fetch them when needed. There is no real performance gain to cache them.
    And the cache might only result in conflicts in case somebody changes the system colors while the cache is active.



src/widgets/kpropertiesdialog.cpp (line 2807)
<https://git.reviewboard.kde.org/r/128283/#comment65517>

    Not sure, but is QRegularExpression doing exact matches by default? IIRC other than QRegExp it does not, but also returns true on partial matches in the given string.
    No time to check in details myself right now, so just asking you to give this a check, unless you are sure it is not an issue.
