Is there a way to send stuff from one platform directly to another if they are in the same orbit? Or is the only way to achieve this, to send the items to the planet first and up in space again?

One thing that I might have missed, is it possible to have multiple space platforms? I tried to find if it was explicitly called out. In the post, it does refer to "platforms", but will it be possible to have multiple platforms? I can imagine how useful it would be to have purpose-built platforms ...

So let’s say two players. Both are building a big power plant. Player A undoes (is that a verb?) something. Player B puts something at the same location A has undone. Now A redoes it. What should happen? Just deny to “overwrite” it seems a bit too simple for me...
I'm pretty sure that there is ...

because the states of this redo can happen at each stage of undo and internally it's then a complex tree instead of a simple queue.

I don't see a need for such complicated logic. I'd implement this similar to most undo/redo implementations I know: As soon as you change something, the redo queue ...

Is this feature (or something else to resolve the problem of accidentally undoing something and not knowing what) on the roadmap?
