I don't think we have a display showing us how much emergency life support we have left. This would be nice info to know without having to turn off the life support. In case I forget how much I have already used.
Example case: Exploring.
I only want to use mats for resupplying the emergency life support in case I have properly used it, meaning it is nearly empty. However, If I forget that I have mostly used it up and only have seconds left and I start to repair my life support without realizing it, this will end up badly. In that case, before starting a repair I could just look up, how much time I have left on the ELS.
