The two "Market" buttons on the bottom left have weird icons.

I am not really sure how a bar graph and a gear represents the Market and your Rust Inventory. Furthermore, why not call it Inventory instead?

Graph - Stocks, Rates, Etc
Chemistry - Creation Area
Gear - Gear, Equipment, Settings

Idk makes sense to me, but there is another issue in that image, the gear should be called Inventory.

I guess those are just placeholders.
