1) Mech Class (light, medium, heavy, assault): Different icon for each.
2) General Mech Condition. Possibly do this with shades of color with more and less damaged mechs showing differently.
On the targeted mech overview you could add:
A) Mech heat level

C) Whether the mech has jump jets
Additional items to consider:
Rear sensors should be added. Rear sensors strength could vary by mech but right now it's pretty bad that we don't have the equivalent to a rear camera so at least let us know something is back there.
