Improvements
* Balancers can be suspended on pillars, similar to transports or connectors. Other transports or balancers can be built on top of them, allowing for truly multi-level conveyor networks.
* Logistics now won’t schedule delivery jobs if the second leg of the trip is not accessible. This solves issues where trucks were being loaded with material and was then unable to deliver it to its destination.
* Trucks no longer get stuck on unreachable goals; they mark such goals as inaccessible instead. Targets that can’t be reached by multiple vehicles get reported via a notification.
* Molten transports and balancers can now be elevated, but must still remain flat.
* Initial transport placement no longer requires a valid pillar to start the transport construction.

New UI
* New user interface for the main menu, map editor, in-game settings and difficulty configuration.
* Revamped save/load game screen to group saves by game sessions. This is also reflected on disk where games from one session are organized in directories.

Changes in the early game
* Abandoned radio tower is now set to be recycled by default.
