Use masked Kirigami icons with explicit theme colors for shell controls so the Shift icon theme renders reliably across light and dark surfaces. Replace the status-bar battery helper with theme icon names so battery glyphs also come from org.shift.icons.
Give the app-thumbnail close affordance a symbolic white X on a dark circular backing so it remains visible over previews.
Reshape the convergence quick settings into a compact
promoted grid and add Clipboard, Disks & Devices, and a
drawer-hosted System Tray popup.
Retry applet popups when their full representation becomes
ready so the desktop utilities open reliably.
