When activating Fog, you also have control over your viewing range where the
world of clipped with the maximum distance. At least this is the behavior on
my pc. I would like to suggest a 3rd variable for this.

currently:

min distance
maximum distance

and I'd like to add:

clipping distance

Example:
You set min distance to 0, max distance to 90, the background color to dark
blue like the midnight sky box, and you end up with a dark blue haze which
is gradual and adds some nice depth. However, the mountains off in the
distance are very clearly being clipped at 90, the effect is really nice
except for this clipping, but to eliminate this you set clipping distance to
150 which may not eliminate the clipping altogether, but does dramatically
reduce it, thus making the fog and depth effects much more realistic.

Small clarification to below example. At 90 fog is maximum gradient(solid
color), thus from 90 to 150 all objects would be solid in color.

That isn't how fog clipping works; as far as I know they can't be separated unless you want AW to implement a separate kind of fog (like volumetric), but it most likely won't give the same effect. A better fog clipping design would have the fog gradient adjustable so more "weight" can be put closer to the minimum distance, for example.

I don't like fog clipping much anyway and any chance I get in games I disable it immediately and just use straight clipping.

Not many games let you do that do they? I thought they put fog in to make it look
more realistic instead of the world just ending suddenly (I haven't seen a game yet
that lets you do it at least).

Most games don't, which is why I said "any chance I get". Off the top of my head, Morrowind can do it but you have to set it in an INI/config file or something. The reason I don't like clipping fog is because it tends to be too close and the fog makes it harder to see right up to the clipping point--it's bad enough when the far clipping plane is so close but the fog only makes it seem closer.
