Workspace Infolets are new (with 20D), configurable mini-workspaces that provide UX continuity between the
Workspace and Infolets on the Task-based Home UX. These new infolets are
sourced directly from Workspace, with any top-level object in workspace
- even custom objects - being an option for an Infolet. Six infolets
come out of the box (Accounts, Contacts, Leads, Opportunities, Tasks,
and Appointments) and four blank infolets are available to customize.
