How many times have you grabbed a Flat Lift, for example, only to find out that you really needed the U-Shaped Lift? I've lost count how many times that or something similar has happened to me.

It would be nice if the two types of Lifts, three types of Connectors, three types of Balancers and two types of Sorters were instead represented as four generic pieces: Lift, Balancer, Connector, Sorte…

During game play it is possible to open the resource overlay (key L) and then enable or disable the display of certain resources such as iron ore, water, coal, etc. However, the selection of resources to display (or suppress) does not persist across saves. It would be a nice quality-of-life feature to persist resource overlay filter settings.
