- Profile name field in the editor (rename, with empty/duplicate checks);
"Edit profile" becomes a submenu listing each profile plus "New profile…".
- "Send button output to the PC" toggle: editor sessions route keyboard/mouse
and joystick through gates (GatedInputSink/GatedJoystickSink) that stay closed
until the user opts in, so editing never injects input by default.
- Save profile now confirms ("Saved ✓"/"Save failed") — the write was silent.
- A lit button renders dim at idle and bright only when physically pressed, so
the press stays visible (three states: off / dim-lit / bright-held).
