SUMMARY If I right-click a titlebar and choose "More Actions", there is a button "No border" that I can use as configuration for said window for the rest of its lifetime, but this setting cannot be set as a window rule for the window manager. STEPS TO REPRODUCE 1. Open some app. 2. Right-click the title bar. 3. Select "More Actions" -> "Configure Special Application Settings" -> "Add Property". OBSERVED RESULT Doesn't offer "No border" as a property to add there. EXPECTED RESULT Should let me add property "No border".

It's called "No titlebar and frame" in the Window Rules KCM. Since these strings don't match, we should probably make them match to eliminate this confusion.

Use more user-friendly terminology for border actions everywhere The window rules KCM calls this "No titlebar and frame", but different less user-friendly terminology is used for the context menu action and the global action. Let's unify them using the more user-friendly name. FIXED-IN: 5.27 M +2 -2 src/useractions.cpp https://invent.kde.org/plasma/kwin/commit/0075f7bd16b1c873bf8e4a73d589cfb9354b0f01
