My Suggestions:
Workbench:
It should be possible to have a functional Workbench/Science Table with a little 3d Printer on it. So you could craft some tools and meds.
Vehicles:
Either a vehicle with a fixed ressource tank or a palette with already functional and fixed resourcetank on top. Would make things easier.
Supply drops:
I like the idea of supply drops, like in the competitive mode. Only it should be called only with the communications antenna. And it should take some time 24h or so and drop randomly on the map.
Science Instruments:
I like the idea of building some science instruments on the planet surface -> windspeed meter, meteorological instruments, Soil probe drilling -> maybe impliment this in a science tree for special survival equipment.
Survival:
1. A emergency tool box, with all the most important tools and survival equipment to produce in a 3d Printer. So i can take it on a expedition.
2. Open Container boxes to drop items in it and Close of with a top cover.
3. Safe Container with lock
4. Approximation warning grid for the base - sounds alarm if someone is entering an area.
5. Alarm pole, to send Alarm codes to other persons in range.
6. Dangerous Materials (radioactive, fuel) - so you have to handle it carefully - can explode and hurt people.
7. Special resources locator tool / drill
8. Equipment malfunctions: like a possibility that the suit will get a leak and you have to fix it. Machines have a malfunction and need repairs. Overheating or filter must be cleaned to run properly again.
Bright and directional working lights:
Sometimes working in the dark could be more relaxing with directional and bright working lights.
Power control:
Possibility to connect all power using Equipment to a command-central (inside/outside of structures), where you can swith on/off things. A emergency power off button or switch all unimportant powerusers off in case of a storm or something, that could damage equipment, when still running.
Fitness Tools:
All cosmonauts need also Fitness -> Bikes to bring Fitness up.
Workstatus lamps:
Full or Malfuntion red/green lamp on Drills - so i can see which i have to fix or empty.
