New IVA system

(Sorry. I am Korean and I used a translator. So this article may contain some misinformation and appreciate the comments.)
I had a lot of fun playing this game, and now I have an idea for a better game. It is the new IVA system! So far, we have not used IVA in capsules or space stations. Therefore, I propose this, and it is as follows.
Implementation of IVA in capsule,
convenient direct interior space station module,
addition of hatch docking port,
some finished space furniture,
better parts for space station,
airlock system,
etc.
Thank you!
