Larger projects are typically broken into areas or Plans. Projects can have many plans, depending on the size and complexity of the project. 

Each plan will have multiple Lanes. There is no physical limit to the number of lanes, but consideration should be given to the practical challenges of too many lanes (e.g. scrolling, complexity, speed). Tag dependencies can be set across lanes. 

An Activity  may have several tags or cards, corresponding to the number of days in the activity. 

Each Tag represents work to be done in one day.
