Thanks for the response! I look forward to seeing this mod progress.
By the way, what exactly would you like to configure using signals?
The minimum cargo setting is what I was thinking about. With Seablock/BA, there are a lot of train upgrades, so I find myself continually wanting to adjust this across my entire base. Having to go into each (of 300) station is a pain. Would also be nice to be able to set request/provide amounts separately.
Also ran into some weird behavior, that I'm not sure if is a bug, or me not understanding how things are supposed to operate:
I had compound deliveres off on both stations, and I had a train get dispatched requesting the two items that were in the sending station. The really weird thing was that during load, the expected load values kept flipping back and forth every tick. For example, one tick iron=60k, coal=20k. The next tick coal=60k, iron=20k, and so on. Turning compound deliveries on seemed to fix that issue, but I'd rather not have compound deliveries.
When laying down a dispater next to a station, a little line appears between the two. This makes me think that the dispatcher and station are already connected, but I still had to connect a wire, which was confusing. Does the line actually do anything? Maybe make the wire not necessary.
