 `omarchy setup input <engine>` installs the selected engine, restarts the supervised Fcitx unit so it discovers new addons, and appends the engine through `InputMethodGroupInfo`, `SetInputMethodGroupInfo`, and `Save`. It keeps the group name, layout, existing methods, and their layout overrides. There is no parallel unsupervised daemon. A per-user D-Bus activation file delegates `org.fcitx.Fcitx5` to `omarchy-fcitx5.service`; it is loaded before live restart.

 Keyboard selections are persisted as data in `~/.config/omarchy/keyboard-layouts`; `default.hypr.keyboard.selected()` reads them before falling back to installation defaults. Personal Hyprland overrides still take precedence. A save reloads and validates the compositor, aligns the Fcitx group's primary keyboard with the leading layout/variant, and restores the previous configuration and group on failure. Non-Latin selections keep the installer's Latin-leading rule for desktop shortcuts. System console, disk-unlock, and greeter layouts are unchanged.

Clicking or pressing Enter toggles an option without closing the menu; Apply returns a JSON array in option order, including `[]` when all choices are deselected. Cancellation still exits 1.

+With `--on-change <JSON command array>`, each toggle runs that command with the proposed selection JSON appended as its final argument, and no Apply row is shown. The checkbox changes only after the command succeeds; a failed command retains the previous selection. Changes persist when the menu closes. The typing selectors use this mode.
