When using Deconstruction Planner, it highlights deletable items. Would it be possible to use this feature when placing Mining Depot?

Another possibility would be that when using the Blueprint tool, it displays the number of blueprinted items (how many of each it has under selection). Could the number of expected resources be displayed the same way while placing the Depot?

Or when hovering over Mining Drills, they display expected resources, that might be used too.

I think the only way I could do it, it would tank performance everytime you hovered a depot,
Since it would have to iterate over all the resources and highlight them

Also for the expected resources, you can just hover the patch in the map screen
