I kinda like those texture control icons...the thing is it should be a FS ship, not some random one...like a Herc or perseus or Orion 
Err.. you don't want to see my attempt at a Herc

Using the 3 constrains and 2 locks is too much
Suggestion:
1: - get rid of the lock buttons. use left mouse for X, middle for Y and right for Z
or
2: - get rid of the lock buttons. left mouse for x, right for z and Y ends up being used on both.
or
3: - keep lock buttons. (eg - for xy constrain) clicking X will toggle Y off, clicking X again will unlock X and ungrey Y
The grid gets displayed for the model AND a smaller grid for the item you are editing. This makes finding the edited item (eye point etc) a bit hard since it is surrounded in grid. Maybe just keep the main grid. Part of the problem is that the default item placement is 0,0,0? so you need to switch to wireframe to find it. Any one using the grid may not find the item straight away. Or you could make the default normal 10 instead of 1. Maybe a fighter/capship toggle with cap ships set to 100 or something.
Also the texturless solid mode seems to use just black (no lighting), and on a black background...

I think you will need to add three views for ortho mode - front view - side view - top view
Most people tend to switch to one of the ortho views for precision placement when modeling, and this would help a lot.
