This feature is available in all editions.
In any grid, you can rank your most valuable work items by dragging and dropping them up or down to their prioritized position in the backlog. This allows the team to see the order in which they should complete their work items.
Good to Know
The most important work items display at the top of the backlog. These are the items that should be considered completing in the current or next release or sprint/iteration. The least important items are farther down the list.
You can use filters quickly rank a large number of work items.
