-### 29. Laptop docking / external-monitor UX `[human]` (needs hardware)
-(Raised by Bernardo, 2026-07-07.) The shipped display application is
-weak and unintuitive, and Hyprland's model for workspaces across
-multiple monitors is unclear to users. Make docking a laptop to
-external monitors first-class:
-- **Unplug → restore the panel:** when the external monitor is removed
-  and the laptop's own panel is off (was the only-active output while
-  docked), turn the internal panel back on *immediately* — never leave
-  the user staring at a dead lid.
-- **Plug → extend by default:** a newly connected external monitor
-  should *extend* the laptop panel (not mirror), out of the box.
-- **HDMI audio:** an easy way to route audio to the monitor when a
-  display with audio (HDMI/DP) is connected — a menu toggle / quick
-  action, not manual pavucontrol digging.
-- **Workspaces + multi-monitor:** document (cheatsheet + menu) and,
-  where sensible, sane defaults for how Hyprland binds workspaces to
-  outputs so multi-monitor behavior is predictable.
-Likely a `hyprland`/`kanshi`-style profile layer plus a menu surface;
-split into slices before starting. `[blocked:hw]` for the real
-dock/undock + HDMI-audio verification (see HARDWARE-QUEUE.md).

+- **[security] System-wide AppArmor confinement**:
+  Enabling `security.apparmor.enable = true` tightens the security posture of the workstation. It confines services and applications to their minimum necessary privileges, shielding the system against zero-days in desktop apps (like PDF viewers or media players). The cost is low (a single NixOS toggle that pulls in the default profile set), and it provides a critical layer of defense-in-depth for a daily-driver workstation.
+
+- **[usefulness] Wayland-native color picker (`hyprpicker`)**:
+  Designers and developers constantly need to sample colors from the screen. Adding `hyprpicker` and binding it to a keyboard shortcut (e.g., `SUPER+SHIFT+C`) gives a fast, Wayland-native magnifying glass color picker that freezes the screen and copies the hex code directly to the clipboard.
+
+- **[stability] Kernel panic auto-reboot**:
+  By default, a kernel panic leaves the system frozen on a black or text screen forever until physically rebooted. Setting `boot.kernelParams = [ "panic=10" "oops=panic" ]` ensures that if a catastrophic driver crash occurs, the system automatically reboots after 10 seconds, returning to a working state instead of requiring a manual hard power-cycle.
