Folder
A folder on the canvas that holds blocks: a back panel with a tab, up to three blocks peeking up as cards, a frosted flap with its name and count; fans on hover, opens wide when a block is dragged over, swings shut when one lands; six paper colours.
Use it for
- Blocks put together by dropping one onto another, by ⌘G, or by the evening sort.
- Anything that should be kept together but not take space (one container, two states).
Don't use it for
- A place you are working in: unfold it into its region (Region with the same hue).
