doesn't return. Plus 36 battery/power quick menu (move the threshold
toggle into the rofi System submenu + a battery-icon power menu, mockup

+### 31. rofi search broken under rofi 2.0.0 `[bug]`
+(Raised by Bernardo, 2026-07-07.) Typing a lowercase query fails to
+match (`steam` doesn't select **Steam**) and Enter launches the first
+entry instead (ghostty) — i.e. matching behaves case-sensitively and the
+selection never moves off row 0. **Not a missing config key:** the
+generated config already sets `case-sensitive = false`, `matching =
+"fuzzy"`, `sort = true`, `sorting-method = "fzf"`, and `rofi -dump-config`
+shows rofi 2.0.0 honours them (they're its new defaults). The lock bump
+`8fded63` pulled **rofi 2.0.0** (a major version) — this is a 2.0
+behaviour change. Needs interactive repro on a session (can't be
+eyeballed headlessly). Candidate levers to A/B live: `matching`
+(normal/prefix vs fuzzy), `-i`/`case-smart`/`normalize-match` (new 2.0
+knobs), `sort`/`sorting-method`, and the per-modi `sorting-method:"name"`
+default 2.0 shows for drun. Fix once, then bake into
+`programs.rofi.extraConfig`. Covers Bernardo's item 1 (case-insensitive
+search).
+
+### 32. SUPER+? cheatsheet bind still not opening `[bug]`
+(Raised by Bernardo, 2026-07-07 — item 2.) Item 26's fix (SHIFT in the
+bind modmask so the shifted `question` keysym fires) shipped, but SUPER+?
+still doesn't open the keybindings cheatsheet. Re-diagnose: confirm the
+Hyprland bind's modmask/keysym against the *actual* layout, whether rofi
+2.0.0 changed anything, and that the cheatsheet path still resolves.
+
+### 34. Menu "Back" shows double arrows `[bug]`
+(Raised by Bernardo, 2026-07-07 — item 4.) The shared `↩ Back` row draws
+a glyph arrow in its label AND an icon arrow — two arrows. Drop one (the
+row icon or the inline glyph) so Back shows a single arrow. One fix in
+the `back`/`row` helper in rofi.nix; applies to every submenu.
+
+### 40. Display rofi menu "Back" doesn't return `[bug]`
+(Raised by Bernardo, 2026-07-07 — item 10.) In System › Display, the
+Back row fails to return to the previous menu (other submenus' Back work
+— cf. the item 24 audit). Trace the Display handler's Back case /
+dispatch target.
+
+### 39. Icons in the power-profile rofi menu
+(Raised by Bernardo, 2026-07-07 — item 9.) The power-profile picker
+(rofi.nix `power-profile`) lists profiles as bare text; add per-profile
+icons (performance/balanced/power-saver) like the other System rows.
+Small.
+
+### 36. Battery / power quick menu
+(Raised by Bernardo, 2026-07-07 — items "battery toggle in a rofi
+submenu" + item 6.) Two slices:
+- (a) **Move the charge-threshold toggle into the rofi System submenu.**
+  Iteration #55 put it in the gum control-center; Bernardo wants it as a
+  first-class row in `nomarchy-menu` › System (self-gated on the
+  `charge_control_end_threshold` sysfs node), reusing the preset picker.
+- (b) `[human]` **Battery-icon click → a dedicated power menu** offering
+  charge threshold + power profile (and switching backend to TLP when
+  relevant). Bernardo will provide a mockup ("when it's time") — hold
+  design until then. Pairs with the instant-effect follow-up in PROPOSED.

+### 33. rofi page-overflow hint (scrollbar)
+(Raised by Bernardo, 2026-07-07 — item 3.) When a list/grid overflows
+onto another page, nothing signals there's more below. Add a scrollbar
+(rofi's `scrollbar` element) or a "more ↓" hint, themed to the palette,
+on the launcher grid and the long text menus. Check rofi 2.0.0's
+scrollbar support/theming.
+
+### 35. Right-click volume → audio control app
+(Raised by Bernardo, 2026-07-07 — item 5.) Right-click the Waybar
+`pulseaudio` module to open a mixer (e.g. pavucontrol) in a floating
+window. Wire `on-click-right` in `waybar.nix` AND the whole-swap jsoncs
+(parity rule); add a Hyprland `windowrulev2 = float` for the mixer.
+Ship the mixer in the template's `home.packages`. Pairs with item 41.
+
+### 37. Default video + audio players + mime associations
+(Raised by Bernardo, 2026-07-07 — item 7.) Install a video player and an
+audio player by default in `templates/downstream/home.nix`, and wire the
+mime defaults (item 8's `xdg.mimeApps` surface) so audio/video files open
+in them. (mpv already the video default per HARDWARE-QUEUE — confirm and
+extend to audio; pick the audio player.)
+
+### 38. Capture-to-file keybinds
+(Raised by Bernardo, 2026-07-07 — item 8.) Add binds for "capture region
+→ file" and "capture screen → file" (distinct from the existing
+clipboard/recording capture flows), landing PNGs in ~/Pictures. Add to
+`keybinds.nix` (single source → Hyprland + the SUPER+? cheatsheet) and
+the Capture menu; reuse the existing grim/slurp plumbing.
+
+### 41. Floating-window audit
+(Raised by Bernardo, 2026-07-07 — item 11.) Decide which windows should
+open floating by default (config dialogs, pavucontrol, file-chooser
+portals, calculators, etc.) and add the `windowrulev2 = float` rules in
+`hyprland.nix`. Enables items 35/36b. Produce the list first, then the
+rules.
