Mirroring is an extremely powerful feature in Factor. Mirroring a card or stack allows it to appear in more than one workspace at a time. This is great for many use cases, including but certainly not limited to:
A manager making a board that mirrors in the top priority stack owned by each of their direct reports
A business unit leader mirroring a business unit’s high-level priority stack into every workspace executing a subset of that priority
Mirroring all the most important stacks you are working on into your personal workspace (which can be found at the top of the left panel)
Mirroring a stack into all the workspaces where a piece of the work is being managed or executed
How do I mirror a stack or card?
Click on the stack or card's three-dot menu.
Click “Move or mirror”.
Click "Mirror".
Click on the workspace or stack you would like to move the item to. If you don’t see it, search for it in the search bar, then click on it.
If you're mirror a stack, the selected a stack will appear on the workspace you’ve selected. It you're mirroring a card, it will appear in the stack you've selected. It will also gain a new icon to signify that it has been mirrored. The icon looks like squares stacked on top of each other; the top one has a + sign on it.
To check that the stack or card has been mirrored properly, hover over the mirror icon and a popup will show all the places where it is mirrored.
