They'd probably jam well before 500°C so no. They would however be good for self-sustaining on aquilo.

Since any cargo sent to a full space station vanishes into thin air, I think it would be appropriate for the game to warn you whenever the sent cargo is about to exceed cargo space.

A small quality of life improvement would be to allow copying entity settings from a nuclear reactor and then pasting that to a requester chest.

Since cooling is now a thing, a fifth tier belt that ties with it would be interesting. SInce it's moving at so fast speeds the belt will generate heat and will jam if it overheats. To counter this, the belt would allow for attaching heat pipes to it. What would tie this to the rest of the gameplay ...

Quality is a problem if you have varied qualities of modules available for upgrade. Like say I have one stack or rare quality and one stack of uncommon quality modules. If I wanted the bots to use both, I'd have to create a rule separately for both qualities.

Issue description:
If I start a recipe on the space platform, request resources for that recipe and then change out of that recipe, the request from the rocket silo still persists.

Steps to reproduce:
1. Choose a recipe on a space ...

I feel it would be approritate if better quality barrels held more liquid. I saw rare petroleum gas barrels being an option while unpacking them today and it got me thinking that having them contain more liquid would be a nice improvement.

This I strongly agree with. If you take into account all of the qualities, you'll probably need to create an upgrade planner with hundreds of rules.
An "Any module" option in the "From" column and "Any quality" option in the "To" column would reduce these instructions to a single line.

Ah, my bad.

If I place underground belts on a gap on a space platform, the belt sort of creates an impossible visual.

To fix this, I suggest adding a belt that dangles between the platforms.

This is a very minor issue.

Oh please make level 4 belts out of this mechanic. Because of the high speed, the belts would generate a lot of heat. On aquilo this would be a benefit since the belt would generate its own heat, but on any other planet they would require active cooling. Faster belts on nauvis for example would need ...

One thing that came to my mind while reading this was: What if you were forced to airlift the captured nests to move them like you can do with Terran units in Starcraft. First you need to go hunting for nests and then you need to bring them back to your base via air. It would be unique, but would ...
