SUMMARY Edit multiple KCMs in parallel. (A generalization of https://bugs.kde.org/show_bug.cgi?id=503767.) STEPS TO REPRODUCE 1. Have a KCM open in System Settings, have unsaved changes in it. 2. Open another KCM, e.g. via Plasma UI. Examples: * Create new activity (as described in https://bugs.kde.org/show_bug.cgi?id=503767) * Click Network icon in system tray -> Configure network connections. OBSERVED RESULT System Settings requires that user chooses to save or discard or cancel. EXPECTED RESULT There should be a possibility to make changes in parallel, as long as the user edits two different KCMs. I think the current behavior is a regression since KDE 4 (or later) because back then one could open a KCM without the whole System Settings UI, and the KCM window could coexist with another full System Settings window and with other KCM windows.

I think this is worth considering, especially since this used to be possible.
It's intentional that the System Settings app itself only opens one KCM at a time. If you have a use case that benefits from making changes in two KCMs in parallel, you can open the second one using the command-line `kcmshell` program (e.g. kcmshell kcm_activities).
