Hi there, thank you for your useful mod. I'd like to report some issues I saw in your entity to category mapping.

The entities from the mods below appear on the "Logistics" tab and I think should all be on the "Transportation" tab with the other train entities from vanilla.

Maybe you can make your mod more robust by updating it to find train related modded entities given some criteria to catch other similar issues to this in the future? Please reply to this thread when this issue is resolved. Thanks again.

Thank You! Issue will be fixed in next release.
I was considering adding some automated system, but decided that if a mod decides that it want to have its own custom item groups (rows in crafting menu), it will be safe to adjust its position manually to make sure it's correct. For example, the automated system i had in mind would have left the 'Current collector' and 'Control station' in the 'Logitics' tab because there are no train-related items (no trains, wagons, rails...).

Thank you for the quick reply.Interesting note on the automated system since 'Current collector' and 'Control station' are only used for trains even though they are not specifically trains,wagons, and rails. So, I think the train related group is larger than just those 3 types.

The item types i would be looking for in the automated process would be Locmotives, Cargo and Fluid wagons, Artillery wagons, Rails, Signals and Stations. It would take any row that contains an of those item types and move it over to the 'Transportation' tab. The issue is that the 'Current collector' is only a crafting item, otherwise unrelated to trains and the 'Control station' also doesn't relate to anything that would normaly be automatically sorted (in code it's only a 'thing that uses electricity').

Maybe one of your algorithms/functions can look for "If entity is not already categorized by another algorithm ('related' to transportation tab in some other / more formal way), then look at mod name for 'train'. If 'train' is found, then sort any remaining entities from that mod to the transportation tab. Just a thought. Cheers
