Compas in realism mode and sprint toggle
The last time I checked, realism mode didn't have a compass. It did have a minimap when tactical view is toggled, but I think it will be great if a compass is visible all the time, and it's swapped to a minimap when the player uses the tactical view.
Also, it would be great to have a "toggle sprint" shortcut. My Logitech keyboard doesn't allow "Shift + W + Space" key combination (to force players to buy their gaming keyboards), so I'm unable to jump while sprinting. And that's a pain in the *** on Mamayev for example, as I can't jump over trenches.
