+    summary:
+      "A big visual refresh: the “glass over image” dark theme, a redesigned top bar, and one unified floating panel system for filters and playlists.",
     features: [
       "New background image: in dark theme a subtle backdrop, tuned to your colour scheme, now sits behind the app — so the frosted-glass surfaces have real depth to refract. Turn it on or off, and dial its strength, with the new controls in Settings → Appearance.",
       "Two new colour schemes: Starship (deep-space blue) and Matrix (terminal green).",
+      "Redesigned top bar: the module name sits in a floating pill with back/forward arrows to step through your modules, and each module's search moved into a matching floating search bar.",
+      "The Feed, Plex and Playlists side panels are now one consistent floating system — collapse any of them to a slim tab beside the navigation, reorder and hide their sections, and your arrangement is saved per panel.",
+      "The navigation rail is now a floating rounded panel too, matching the rest of the app; at high browser zoom its list scrolls without a scrollbar, with a soft edge fade hinting there's more.",
+    ],
+    fixes: [
+      "Repeated identical notifications now fold into a single entry with a count, instead of stacking up.",

     chores: [
       "Reworked the translucent “glass” surface system so the whole app shares one consistent, tunable look.",
+      "Retired the German interface language; Siftlode is now available in English and Hungarian.",
