At the moment the level bombers are probably the most handicaped pilots.
While aiming - they cannot see anything. They have to have the prinded-out bombing tables and conversion handy; and mph/kmh tables as well, plus they hardly can see any terrain. The navigator position in TB-3 was actually PRAISED for a good visibility from it -- all-round and extensive bottom glazing. In game it looks and feels more like flying in a tank - you can not look out, and most of the screen is the interior of a navigator's cabin. The same applies for of most other bombers, by the way.
Maybe there is a possibility to make a navigator workplace to look something like below - with most info at hand, and a possibility in an instant to switch from a bomsight view to the navigation view. And the full set of bombsight controls, so the navigator is not forced to memorize lots of keys.
