Please add tooltips to all the little heads that show what the unit is effective/ineffective against

The line of little heads in the unit cards that show what units a dude is effective against, and what ones they are susceptible to really needs to have tooltips to tell us what they are. It's nearly impossible without having played this game for hours and hours what those little heads represent.

Please add tooltips to tell us what these little icons are.

Thank you!
