Port away from KMoreTools
The idea behind KMoreTools was to point the user at external tools for a given job.
It provides a rather complex framework for that, including suggesting not-yet-installed tools.
The UX behind that isn't great though, which somewhat deep menu hierarchies and a somewhat arbitrary list of tools.
Most KDE apps have moved away from it, with only Dolphin remaining.
Instead provide direct integration with relevant KDE tools (Filelight, KDiskFree, KFind)
