Put a trap down and its icon shows under your portrait, like a shaman's totem, with a clock sweep and the seconds left. It stays clear of your pet's frame
In its last seconds (10 by default) the countdown turns red and the icon flashes, so you know your trap is about to vanish. An optional sound can play too
Lock or move the icon, keep it under the player frame or put it anywhere, make it round or square, show the seconds below or on it, resize it, and choose when and how the warning shows. A test button shows a trap without a real one
