I made a different preview than just Ryen's children this time. In the screenshot below, you can see changes I made to the storage screen of the country overview map.
Green icons = The production of that resource is running
Yellow = The player paused the production
Red = Production not unlocked (research or building missing)
Blue = Repeatable research
Purple = Trainable soldiers (not in this screenshot)
The primary idea is to give the players a quick way to see which productions are active, and what they're missing. Interacting with the red icons will tell you what building/research you need for this resource, since some people had troubles to find what they need for certain resources.
The option to pause production will help when you need a certain resource and don't want it to be consumed as a material for something else. For example, when you need steel, you could pause the production of steel pickaxes for a while.
The blue icon at the bottom lets you pause and resume all productions on a stroage page which require materials at once.
