 - **Ethernet & VPN**: Bring interfaces up or down and connect to VPN profiles from the same Network page.
 - **Bluetooth**: Discover, pair, connect, trust, and forget devices, and power the adapter on/off.
 - **Audio**: Adjust output/input volume, mute, and pick the default speaker or mic; preview a device with a test tone or a live input-level meter; control the volume of individual apps (browser tab, Spotify, etc.) independently.
+- **Power**: Switch power profiles (performance, balanced, power-saver) and check battery charge, health, and time remaining at a glance.
+- **Inputs**: Change the keyboard layout and adjust mouse pointer speed, via `hyprctl` (Hyprland only).
 - **Vim-like Navigation**: The entire interface is keyboard-driven with Vim-inspired shortcuts. Use `h/j/k/l` to move, `gg`/`G` to jump to the top/bottom, `/` to search, `q` to close panels, and more. All keybindings are fully customizable via the config file.
