The facility buildings are the only building type that does not show items/minute scales, it only shows n-number of cranes.
The information that is shown under the items is n/x items required for building present. In a game about making as much as possible per minute, I don't really care if there's enough items for a build.

This is a QoL suggestion, as its goal is to improve the readability of the facility. The information is already technically, but the cranes are harder to read than a plain number.
