Instead of radio buttons and checkboxes, starsector prefers these really subtle colour indications with no distinction of radio buttons vs checkbox choices. So the first like 10 times you see them, you're stuck wondering "does black mean it's pressed, or not pressed?" Like the refit weapons selections.
In the market and shipyard tabs, the colours are also really subtle and the button design in general. They should also more clearly be boldly coloured tabs so you know which market your on immediately.
Examples:
These should be two sets of checkboxes
Those boxes on the right side. Some are mutually exclusive options, some aren't. They should be changed to radio buttons and checkboxes.
This should be more like tabs, with really bright colours or some way to show more obviously that you're in a particular tab. Orange lines with dark orange = selected vs orange lines with black = not selected. This distinction does not POP visually the way it needs to.
Edit: the developer pointed out that the market 'grid' changes colour depending on which market you're in. I've never noticed that. Perhaps it's too subtle, perhaps the icons of the stuff is too well-drawn and thus distracting, perhaps most of the player focus is on their own inventory in the bottom half, not the market, or perhaps i"m uniquely obtuse? Maybe it needs to be toned-up a bit.
This too.
Maybe those options at the bottom of the screen should also be checkboxes? When you start playing the game and you see this row of blue and black squares, it isn't immediately clear which is selected and which isn't. Starsector already has checkboxes. They're really good. Bright blue. Everybody knows they're the best checkboxes. They win so much. Why not use them more?
