I read project readme, checked client side and server side configurations, and no such feature exists
YES

Is your feature request related to a problem? Please describe.
I don't like that I don't have to aim, especially with the FORWARD_BOX, but also with the HORIZONTAL_PLANE. I don't like that a spear or a dagger hits multiple enemies.

Describe the solution you'd like
I would like either a global config, or a weapon attribute to reduce the extra width used for the hitbox. Is this what angle is supposed to do? 0 angle doesn't seem to help with my issue (and isn't used in the hitbox calculation code as far as I can see).
A new hitbox type that is just a raycast could solve my frustration as well.

Describe alternatives you've considered
For now I'll probably swap the hitboxes of builtin weapon attacks to use VERTICAL_PLANE for a lot of them.

Additional context
I'm using 1.20.1

Additional "Additional context"
I'm playing in first person mode. (I assume the hitboxes were tuned for third person mode where more lenience makes sense)
