I checked it out and it looks nice enough.

I mean no disrespect, but I feel I'm repeating myself here:

To find out where you end up when you turn X and thrust Y, you don't
need calculation, tables or measure angles.
It's the other way around: To end up where you want to be, you need to 
calculate and measure angles.

Example:

You're moving at velocity 10" straight "north". If you do nothing, you
end
up 10" north of where you are. But you don't want to be there. Let's say
there's an asteroid right there.  You want to be at a point 1" further
north and 1" due east. How much thrust to apply in which direction?

Easy (this was meant to be a simple example): Turn 45 degrees due east 
and thrust sqrt(2)".

Now tell me how you can get there *without* measuring (or calculating)
the angle (45 degrees) and without calculating the square root of 2?

I'm not sure that's a good idea. The FT system is easier but not 
necessarily more flexible. I think free spinning dreadnoughts need
to be examined thoroughly.

Heavier ships already hold the edge in weapon range. If they can spin
around as nimbly as lighter vessels, it's going to be very difficult to
exploit the blind rear arc.
