On marathon it may take 100+ turns for a free colonist to adapt a profession. In that time it is possible to switch cities and have the free colonist train on the job in several cities. However management of such LbD-colonists among other free colonists is difficult since the info which profession he is learning is only visible when he is on a job in the city screen. It would be useful if tooltips for free colonists in garrison or transport area or on map would show the LbD-status, e.g. free colonist, working to become a lumberjack since 85 turns. This would allow to distinguish LbD free colonists from other free colonists and make handling of them easier.
