I have to ask the question why I can't just type in the amount of cargo I want to purchase and press enter? Much more logical and it'll be so much quicker!
That's the way it should've been since day one. Seriously, when did this simple idea of convenience became obsolete? Because the current GUI has been built around a controller, its simplified usability is, and will always be a limiting factor.
I can only hope, that those new ship UI's will be designed with a mouse in mind. No more of this dreadful and claustrophobic boxy menu after menu navigation.
Stupid consoles handicapping PC players / end rant.
