Thank you for the detailed feedback. It's always appreciated, especially since many of the points apply to the upcoming PC version as well.
I'm building the engine of the PC version with the possibility of doing "undos" built-in from the very start. I also think I came up with a good UI solution for the slipway routing that would let you just drag exports from slipway to slipway - but we'll see how it works in practice. The "kickstarting" is "works as intended", but maybe not "works like it should". Will think about it when coding the new economy engine. The last two are bugs, but they're pretty minor - and at this moment I'm really focused on getting the PC version off the ground, so they might be left unfixed for a while.
I'm planning to have Linux build. Unity supports it, so it's only a question of a little extra elbow grease to get it done.
