[SUG][PLAYER] Lemming count on zombie trapdoors

[Crane]

Currently, zombie trapdoors show the "lemmings remaining" count on trapdoors all the time (tested on level "Last Lemming Standing").  I can sort of understand the need for this because you haven't got the counter on the toolbar to go by - nevertheless, can I suggest the number only appears in "clear physics mode" rather than all the time?  It looks rather unneat and might cause confusion if there's terrain above the trapdoor that can get removed.
