1- a readable label on the container will be very usefull when you have multiple containers near each other.
2- i found many problems managing trucks and truck stations, in particular:
2A- truck AI must be improved so if you set multiple trucks on same route for different resources (naturally with two truck stations, one where load and another where unload for each resource) so the trucks could automatically evitate to collide between them.
2B- if you need to build many truck station near each other, one for resource/route, many times a truck go a little over its unload station, and finally it stop in the area of another station that is supposed to unload a different resource with a different truck. In that condition the wrong station unload the wrong resource and then the station distribute the wrong resources to the wrong factory.
To solve i think it will be very very usefull to have the possibility to set a specific resource in the options of a specific truck and the two truck stations involved in its route, so if the wrong truck goes to stop to the wrong station nothing wrong will happen. A system where only the resource set to a station will be loaded/unloaded.
3-on the the conveyor splitter/unifier is often needed possibility to set up the sequence of split. For example, on a conveyor is running a group of 5 resources: the splitter automatically send 2 on a side and 3 on the other, but u need to send 1 to a side and 4 to he other side. Please consider that option to be manually set by the user.
4- same thing on the containers, if u use one container to accumulate only the exceeding resource running on a conveyor by positioning the container on the conveyor route, is needed the possibility to set the container to take 1 resource on a group of 5 passing trough it, and leave the remaining 4 resources to pass trough and continue its run on the conveyor exiting from the same container.
5- i wish you are considering to introduce more version of the jet-pack, in particular a version that could litterally make the user fly for long long time before finishing propeller (maps are very great, and this is good, but is too boring going to the edges by truck or running, and if u need to do it often like me this could be a real problem that make me leave the game sometimes for days)
6- in certain situations is needed the possibility to switch off or on an entire "factory", but in the game there isn't a switch device.
