The Mk I version of shields, engines, etc should go to the left of the Mk II versions. As it is, the Mk I is after the Mk III. Speaking of that, I’d like to have a little ‘I’ ‘II’ ‘III’ in the lower corner of the icons so I don’t have to mouseover. BTW, mouseover should be instant, no delay, on that screen.
Instead of bunching up the icons in a 5x5 grid, why not break them up by category? Have a line for beam weapons, another for missle, another for torpedo, special, etc?
I’d like to ctrl-drag an already installed part to make a copy of that part in another slot.
