Mirror Blocks: The Feature You Didn't Know You Needed
The same Block, living in multiple blends at once. Edit it in one place and it updates everywhere. Here's what Mirror Blocks are and when to use them.
You have a to-do list that belongs in two places at once.
Your "Client Project" blend has it. Your "Work Dashboard" blend needs it too. So you do what seems logical: you copy it. Now you have two lists. For about a week, you keep them in sync by hand. Then you update one and forget the other. Now you have two lists that tell different stories, and you have no idea which one is accurate.
This is one of those small frustrations that you stop noticing — not because it goes away, but because you accept it as normal. It is not.
That is the problem Mirror Blocks solve.
What is a Mirror Block?
A Mirror Block is the same Block living in more than one blend at once.
Both instances share the same underlying content. Update the content in one, and the change is there in the other the next time you see it. There is no sync button. There is no "send to other blend." It just works, because both instances are pointing at the same content.
What stays independent: the position, the size, and the title of each instance. A mirrored Block can be called "Weekly Goals" in your Work blend and "Goals" in your Dashboard blend. Same tasks. Different names. Neither knows nor cares about the other's title.
You can tell a Block is mirrored by the small teal badge in its corner. That is the "M" indicator. It means this Block is living somewhere else too.
Which blocks can be mirrored?
Mirroring is available on the blocks where your own content lives:
- Note Block
- Text Block
- Todo Block
- Bookmark Block
- Image Block
- Embed Block
- Kanban Board
The Now Block (the live clock) and the Wiki Block (the Wikipedia feed) don't support mirroring. They don't need to — their content is always live and current regardless of where they are.
How to create a mirror
Open any supported Block's settings panel. You'll find a Mirror tab. Pick the target blend from the dropdown, then click "Create Mirror." The Block appears in the target blend immediately, with "(mirror)" added to its title by default. You can rename it whatever you like.
The settings panel also shows you a "Mirror Locations" section: every blend the Block currently lives in, listed in one place. If you want to see the big picture of where a Block lives, that's where to look.
When does mirroring actually help?
Here are a few situations where it earns its place.
The cross-context to-do list. You have a Weekly Goals Todo Block in your Work blend. You also want it on your Daily Dashboard so you don't have to jump between blends to stay on track. Mirror it. Now it's in both places, and checking off a task in either one reflects in the other.
The shared reference list. You save a Bookmark Block of your client's key resources in their project blend. You also want those bookmarks available in your master "Client Files" blend without copying them by hand. Mirror the Block there. One source. Two access points.
The Kanban Board on multiple views. You have a content pipeline Kanban Board in your "Content" blend. You also want it visible on your overall work dashboard for a quick status check. Mirror it. Drag a card forward in either blend and it moves in both.
The note that belongs to two projects. Some notes really do belong to two contexts. A running log of decisions on a client project might also belong in your personal "Lessons Learned" blend. Mirror it. One note. Both blends.
Mirrors only share content. Settings like title and size are completely independent per blend. So you can label the same Block differently in each context without affecting what's inside it.
What mirroring is not
To be clear about what this does and does not do.
Mirroring is not cloning. A clone is a copy that immediately becomes independent — edit one, the other doesn't change. If you want a separate starting point based on an existing Block, clone it. If you want the same content accessible from two places, mirror it.
Mirroring is also not moving. Moving a Block removes it from its current blend and places it in another. Mirror keeps it in both.
One source. Wherever you need it.
The reason Mirror Blocks matter is not the technical detail of shared content. It is the shift in how you think about your information.
Instead of "this information lives in one place and I have to go there to see it," you can say "this information lives where it makes sense to me, and I can have it in as many contexts as I need."
That is a quiet but meaningful change in how organized your life feels.
