I'd like to try to find a mod like this, but I know my English isn't very good, so I'd like to make it clear what I mean first in case I've phrased the request incorrectly. You can also consider this a suggestion for implementing the mod.

I would like to find a mod that can change the default binding of the body position in relation to the direction of view. In the game we can use free view to control the arm weapons, but in this mode we are completely unable to control the position of the body and it would be nice to find some kind of mod that can maintain aiming away from the body with the ability to control the body. In other words, this is the ability to change the standard position of the reticle without being tied to the body weapons, when and if necessary.
  Under normal conditions, regardless of ArmLock, the torso reticle ALWAYS follows the arm reticle. The only difference is the presence of a delay when ArmLock is turned off. We also have FreeView for direct control of the arms, but in this case we lose control of the torso. I want to make it so that I have the opportunity to move the arm reticle and FIX IT IN THE POSITION I NEED without having to use FreeView and so that the torso reticle DOES NOT MOVE to this point. After this, the overall control should remain classic, as in OffArmLock mode, but the reticles should remain desynchronized without the need to hold additional keys and we can control the torso and arms as usual.
  If I try to describe it from the reverse side, then I would like to be able, for example, to “lower the torso” so that it does not pursue the aiming reticle of the arm. To return reticle synchronization, we always have a torso centering key.
  In general... The point is that I would like to be able to freely untie the Arm reticle from the torso reticle, fix the new position point of the Arm reticle and thus continue to control the Mech as under normal conditions.

  I hope that I was able to correctly convey what I am looking for, and if it does not exist, then consider it a proposal for implementation.
