The Flag system is a marking mechanism for cards within the BoondManager application, designed to facilitate the management of your activity. Flags allow you to group and manage sets of cards by theme within the tool.
With this feature, you can create personalized subgroups gathering certain important cards to monitor (e.g.: cards of historical clients, cards of high-potential candidates, cards of leads who have received an emailing, etc.).
To learn more about managing Flags, we invite you to read the dedicated article on this topic.
