Part of the ship part of the crew (Ships and crew management and suggestions)

Hello Community!
It is really cool to be a part of you and play such an amazing game! Thank you Devs!

I know that game is in the early access and many features doesn't exist yet and maybe will never be existed, but I have couple suggestions so far.

First of all, please, give us ability to capture and fix any ship that exist.
For example, the ship of another faction was destroyed by pirate one. I leaved the battlefild (because  I don't have shields, guns and enough crew to fight, only innitial staff) and jumped back when the pirates has gone.
 I found the ship, that now marked as derelict and sent my crew to explore it. 
But! I've found that six members of that ship crew are still alive! They regain oxygen from my shuttle and continue to roaming around their ruined ship. 
They don't fight me, and don't perform any repair works . Some generators are still active and some equipment is still online. 
I wished to help them to fix breaches and repair ship but failed (I do not have such ability). I can only salvage that ship despite the crew is still present and alive. This fact is really hard to understand. 

I thing that it will be more natural to have an ability to fix , capture,  sold, left and utilized any ship in the game  universe. It may lead to conflicts with factions, or persons, it may take an effect to our karma and so on, but ,please give us these options.

And the other one.
Why I can't save those people? 
I can't interact with them, they don't get aboard, they just stay at ship.
I have an option to bring them oxygen using my shuttle or leave them to suffocate. It's awful, you know.

Thank you!

Thank you!
