SUMMARY I noticed that Dolphin's settings menu appears to have 3 different settings that the user can select. I think this can be tough for some users to have to click so many times to find something specific. Ideally, we want to provide users with a one-stop-shop where they can do all things related to one specific activity. In this case, the activity of editing settings is split into 3 different modules. Understanding that our KCMs are all modular, I would love it if we could combine Dolphin settings with the Shortcuts settings, and the Language settings into one UI. That way we make it a one-stop-shop. If the argument is that these other KCMs come from System Settings and are general in their behavior, we should generally link those KCMs to System Settings instead. That way users understand the context of their changes. Otherwise, users can be confused to realize they are changing general settings vs Dolphin-specific settings.
Not specific to Dolphin; these actions are provided by KXMLGui, so the request is applicable to all KXMLGui-using apps.
I agree with this suggestion.
Maybe also add the "About <app>" and "About KDE" pages to the bottom of the settings window, like most Kirigami apps do.
That I'm less sure about; "Configure this app" and "Seek out information about this app" are different tasks. The fact that we combine these in a lot of Kirigami apps is wrong, IMO. And we don't do it universally, either; Discover, System Monitor, and Elisa at least all have separate "About" pages triggered by separate menu items.
