Needs some more details. I can't understand what you mean by saying "resource will not show its resources"

Still don't get it, screenshots are ok for me. Can you tell what exactly is wrong here?

The sources itself do not contain the corresponding colour. Also I know it'll be a pain to code it, hence I gave it low priority.

Sources are almost entirely covered by miners and you can't tell for sure which resources it contains, that's why miners have a small pie chart in the center.
It would be a visual feature but I'm not sure if it is a good idea since it'll add more visual noise. Would be great to hear from other players what they think about it.

The only suggestion that I can give here for now is only for the single resources like in his screenshot 11.png . There is only IN5-AR. Will be little bether if the middle blue circle show us visualy how the resource decreases. I used his own screen to make visualisation of my idea:

You are allowed to sell right, maybe use that mechanic. Tbh I don't care, but it caught my attention 1 day so yeah.

There's also another way to see, that's limited to the type of miner you use. When you add a Miner to a resource, it shows a text line for each resource on the miner, regardless of what is actually there. If a resource isn't there, the listing is shown as black, while if it's there it shows as the color of the resource it's mining. This can be a quick visual reminder of what the miner is getting out of the resource. The downside is if you use a miner that can't mine all the resources, it won't show the non-mined resources, like using a Scalar miner on a pure Matrix resource won't show Matrix in the list, and would show Scalar as greyed out, or if you put a Vector Miner on a Scalar + Matrix resource, it would show Scalar as green, Vector as greyed out, and not list Matrix at all. So, plan your resources accordingly.
