Wow - I have an add-on to add "open with k4dirstat" to the right-click menu. Have used KDE5 since it came out and did not know about that. There is no affordance there at all; it doesn't even highlight on mouse-over.
I get a menu with options for not-installed apps - filelight, kdiskfree and two partition tools. 'sudo apt install filelight' and it works, but TBH I'm not keen on filelight, would be nice to have k4dirstat as an option there (sounds like a bug report is due).
