Pressure Overlay

[RollingThunder8]

Noticing how some areas in the game can get very high pressure - either deliberately as a result of something the player did or just naturally - what would be handy would be an overlay that lets you see, at a glance, what areas are safe to enter and what require special suits. For that matter, ARE there any suits that will protect against popped ear drums in a high-pressure environment? I know popped eardrums "only" cause a temporary stress reaction, but I'd still like to avoid that if I can. I would think the overlay wouldn't need to care about dangerously low pressure, as the only consequence of that IIRC is the breathability of the atmosphere? Which is covered nicely by the Oxygen Overlay already.
