Hi!

I have a few questions which are probably more generally about renaming trains than about this mod specifically :-)
- I guess the inserter-rotation-trick is mainly for loading-stations. Unloading stations technically dont 'need' it?
- Is it correct that this enables multi-item request stations? (by re-labelling to requested item)
- Is it a limitation that the rename occurs when a train leave? (i.e. a circuit condition might trigger after the train has left, for instance if an amount of items fall below a threshold).

1. The rotation trick is meant to avoid a loading stack inserter to be left with a partial amount when the wagon is full and departs, because it may be that the next wagon arriving at this station should not be loaded. For example, my steel furnace stations will only fill every 5th train that comes to unload iron plates.

2. Yes! I have complex production (science, engines, etc) factories all sit directly adjacent to either 1 or two stations, buffer comparison with combinators decides which item is requested next. Combinator settings for these are shown in some of the screenshots.

3. It is very-very important, that when a station is renamed, this occurs before any train is heading towards it, or that train will get its route cancelled and may stop mid track, blocking. At the moment a train leaves, you know exactly which item is next most requested and only needs to be checked again when that train leaves.
