Suggestion - Footprint Indicator in Slots Menu

Hi, I’m a new player but have been enjoying Production Line so far. One thing I’ve noticed is that it’s a little hard to plan out my line with future expansion in mind, especially when dealing with slots that are buried behind a few research milestones. It would be nice if the footprint each slot occupies would be indicated in the menu, so that I could quickly reference it for planning, even if it’s not unlocked for me to build yet.

I’m attaching an image with a mock-up of what I am suggesting - as an example, I have drawn up the “Fit Body” slot layout. I have indicated the stockpile square in red, and also tried to indicate the direction of travel with green arrows. Thanks for your consideration!
