I've finished implementing all the required code for displaying and selecting items in the equipment selection. The "OK" button is disabled unless a valid combination is selected (you must select a main and a secondary item, modifiers are optional).
However, the stats and info isn't displayed yet, just the names. When the screen is fully done, with power, cost, and space usage shown, I will post a new screenshot.
Also, I realized that "Biology" field is a bit too restrictive, since there's not much biological options aside from agriculture and some minor pollution and misc technologies. So I've changed this field to "Construction", which covers different areas that requires engineering such as colony bases, mounts, transport pods, etc.
