Show inputs/outputs when building is selected

Describe the issue

It is not possible to know what inputs/outputs are unless you build a new building. E.g. if I'm clonning the electrolyzers here, and I have no idea what the ports are:

Please always show the input/output materials/substances for "green" and "red" arrow. It would be great to have the same for the "yellow" arrows too.

Additional context

• Game version: v0.3.4

Thanks for the report, we will look into this.

Thanks for you report. This has been fixed in one of our previous updates, selected buildings show their products next to ports.
