Duplicant Skill Manager puts the colony's training controls in one place. Refresh the lists after loading a colony, select a duplicant, and choose exactly how you want to develop them. Add experience or skill points with a chosen amount, learn one selected skill, learn every compatible skill, or reset the duplicant's current training. Matching reset actions are included for experience and skill points when you want to return those progression values to zero.
