In addition to the "Boards" feature there is a story map under the Stories tab with the extra ability to attach and view user stories at each location.
This dedicated story map is ideal for your project's site map or highest level user flow diagram, with individual boards used to express more detailed flows

Workspaces support up to 100 cards per board during the beta period (limits subject to adjustment)
