Clicking "More Appearance Settings..." from the home page doesn't expand the "Colors & Themes" menu in the sidebar when it was last selected. STEPS TO REPRODUCE 1. Open System Settings 2. Scroll down the sidebar, select "Colors & Themes" 3. Click to go back at the top-left of the sidebar 4. Click to go home at the top-left of the sidebar 5. Click "More Appearance Settings..." OBSERVED RESULT You're taken to the "Global Theme" page. The "Colors & Themes" sidebar entry is highlighted as selected but not expanded, so you don't have the Colors, Night Light, Application Style, Plasma Style... entries to click. EXPECTED RESULT The "Colors & Themes" submenu is shown. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora Rawhide KDE (available in About System) KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.6.1 ADDITIONAL INFORMATION
This also happens in Plasma 5, but there i would less often use the "More Appearance Settings..." button as "Appearance" was the first entry in the sidebar.
