I wanted to pass along a challenge that a friend of mine who just started playing encountered while going through the tutorial. During the step where players are supposed to unfit the civilian gun in favor of the light ion blasters he ran into issue seeing where he needed to click to move to the next step. Even though the arrow points in the general region of the unfit module button, it can be hard to see that icon depending on how the ship is oriented.
I have attached a screenshot of the fitting menu, with the ship in the default orientation. Even through there is some contrast, the button is fairly small.
