Atmosphere Percentages?
So I know it tells you the percent of a material which is gaseous, liquid, solid, but is there a way to check the atmospheric composition percentage (e.g. Earth atmo is 21% Oxygen)

I second this. It would be great to have a 2nd panel that shows the composition and effects of the atmosphere separate from the rest of the planet's material.

It would also be nice to include the objective amount/density of particular gases in the atmosphere as humans can apparently withstand and breathe at various atmospheric pressures as long as there is the right amount of oxygen in it. I've read an article on this but there is too much detail to it to bring up all of it here. It would make creating habitable atmospheres/planets for (potentially human) space civilisation much easier and convenient.

So, in short, as long as the amount of oxygen in a mixture of gases corresponds to the amount found in Earth's atmosphere at sea level (20%/21% at around 1000 hPa), the mixture is fit for humans due to the amount of oxygen in it. Therefore, a mixture of gases can contain 40% of oxygen, or just 0,4% (if I remember correctly), and still be fit for humans to breathe because it's all about the objective amount of oxygen in the mixture, not its percentage amount (provided that all other gases in a mixture do not pose any threat at given pressure).

Although, to be honest, an average human is not a professional diver who can withstand extreme pressures in an experiment and thus can withstand an atmosphere where there is enough (and not too much) oxygen for humans (to breathe) but it only constitutes 0,4% of all gases in the mixture. Regardless, I would find such information on a panel (objective, not relative, amount of a gas in an atmosphere) useful. Are there any plans to include this feature in the future?

As a bonus info, the habitable/survivable temperature seem to change accordingly with the atmospheric pressure.

I hope I expressed myself clearly enough, I've read some articles about the subject matter at most a few months ago.
