Hi,
Thanks for making this mod, it has been very fun when combined with Factorio Space Age Without Space. However, when stack inserters are unlocked, loaders do not gain the ability for outputs to stack. I'm not sure if this is intended or not. It seems like they should be able to given that things like miners and recyclers gain the ability to automatically stack outputs, and at the moment the convenience of loaders is offset by no stacking.
There are small mods that add loader stacking (see https://mods.factorio.com/mod/stacking-loaders), but it would be nice to have it built in to Factorio+.
Thank you!
