Many times when using Acumatica a user will click back to orders, shipments, customers, stock items while working in the context of a workflow or a transaction.
This idea is to provide the ability to quickly select from a list the invoice, shipment, order page etc. recently viewed, rather than having to use the workspace or universal search to find your way back to those pages.
This could be accessed either through a toggle on the Menu to alternate between workspaces and recently visited pages, or a drop down from the top pane (i.e., to the right of the search box). The items in the list would be the name or ID of the entity ("Order: XXXXXXX", etc.) rather than the screen name or ID. The list would be most recent at top to least recent at bottom (last 10?).
