I think it would be a good quality-of-life improvement if the weights of equipped weapons, as well as those on the ground, were displayed. As it is, I have to keep dropping weapons until I have enough space to pick one up - it's easy to do for the starting weapons lying around (as they're mostly weight 4), but picking up a teammate's weapon (either to use or immediately re-drop to prevent despawn) can be a hassle since you have to keep dropping weapons to hope there's enough space for it.
