the new combat pace mod is nice, but cause some issues as you can clearly see compared to walking, running, sprinting, ...
additionally having keybindings for all these movement types can get quite complex. in the end i oft think to myself this issue wouldn't be that complex on a controller (pointing at the analog stick).
in the old days when splinter cell was ported to PC they had a nice idea to "port" the analog stick, which could also be used in Arma
You got your normal keymapping WASD to walk around, you can change movement speed at anytime by using your mousewheel... and there were about 5-7 different speeds, starting from really slow walking up to sprinting.
it's just an idea since it would give an even finer movement to Arma. Conflicts with the action menu could be resolved easily i think.
