 2. Highlight that wallpaper as selected in the scrollable pane while it shows in the preview.
 3. Keep the scroll position when a picture is selected. Today selecting a picture snaps the scroll back to the top, which is the bug half of this.
 Grade: minor scroll-reset defect x every panel selection = P3 = [#C]; the open-at-current and select-current behaviors are enhancements at the same level. One type tag, so filed =:feature:= with the scroll-reset called out as the bug. Solo: buildable in the settings GTK panel, agent-verifiable via headless capture plus the wallpaper.py tests, no design call — swww query gives the current wallpaper, and scroll-position preservation and row selection are standard GTK.
+** TODO [#D] Worldclock tooltip blanks on one bad timezone row :bug:dotfiles:waybar:quick:solo:

+:END:
+Found by sentry (2026-07-25), verified by exercising. =hyprland/.local/bin/waybar-worldclock= builds each zone with =ZoneInfo(tz)= inside the loop (line ~99) with no guard, so a single malformed timezone row in =worldclock.conf= raises =ZoneInfoNotFoundError= and crashes the whole python pass. The tooltip then renders empty and *every* zone is lost, not just the bad row; the traceback only reaches stderr, where waybar never surfaces it.
+Repro: a conf with =America/Chicago|Home=, =Not/AZone|Bad=, =Europe/London|London= renders =tooltip: ""= (Home and London gone too).
+Grade: minor severity (one module's tooltip blanks, no data loss) x rare edge case (a malformed conf row) = P4 = [#D].
+Fix: wrap the per-row =ZoneInfo=/=datetime= in a try/except and =continue=, so a typo drops only that row and the valid zones still render. Solo + quick: the script already has an env-override test harness (=WAYBAR_TIME_EPOCH=, =WAYBAR_WORLDCLOCK_CONF=), so a red-first test is cheap.
 ** DONE [#C] Floating layout — should we? :feature:hyprland:
