PD:
The red X vs green Checkmark is used on the checkboxes. Yes and no, respectively.
If I come across a good way to do without, I'll remove them...
The yellow boxes will be for the Leaky Shields, once implemented.
That's an ancient bugtest... Oddly enough it isn't actually a requirement anymore, so I don't know why it would show up... time for another bug report I guess
Names could use a bit more conciseness, I suppose. More tidying up to do for next version.
The polar grid background just looks cool, IMO
You can always just delete the UI bmp to default back to normal.
Lack of piercing is just fine. The combat system is based on CBmod, where there wasn't armor-skipping either. Although sufficiently focussed firepower does penetrate, since the armor is directional.
