Prioritizing content within a Planner feed will move the item to the top of the queue, regardless of the order in which the feed is optimized.
There are a couple of different ways to prioritize content. One way is to click on the Prioritize button. You see this when you hover over an item in the feed.
Click the button to move the item to the top of the queue.
To remove an item from Priorities, click the "Remove from Priorities" button on the item in the Priorities Queue.
Another way to prioritize content is to drag and drop content from your feed's stream. Simply click on the item within the feed, then drag and drop within the Priority Items area.
Excluding content from a Planner feed will remove the item from the queue. To exclude content from a feed, click the three-dot menu on the item in the queue and select "Exclude item."
The item will disappear from the feed.
If you change your mind, go to the top of the feed and select "Show Excluded." This will display all excluded items as grayed-out, instead of removing them all together. You can click on the exclusion icon ⊘ in order to allow the item back into the feed.
