After some time of fascinating playing Factorio I want to say about some things that are uncomfortable in the current version. Meaning graphical representation of resources:
1. Stone resources are hard to notice and differ from the default terrain(even big deposits). In nighttime they are almost completely invisible. I think you can make them brighter to make them easier to spot.
2. Minimap representation of stone and coal. I may be wrong but it seems that currently coal is not displayed on minimap at all. At least I can't see any representations of the big coal deposits on minimap. I have to bring up global map from time to time when searching for coal. The same goes for stone deposits. I think they should be visibly marked on minimap like iron and copper deposits. When I look on mimimap, I want to see info about my surroundings, at least I desperately want to see coal info on in

Thank you.
