Region
A drawn rectangle with a name that carries a rule: Well(region) with a head (Label name, Label rule, Label count) that lights as a drop target, dims, hides in the past and renames in place; a pinned lens is Surface(lens) with Row(list) rows.
Use it for
- Arrangement that means something: Done ticks what lands, To do and Doing make tasks or reopen them, This week, friday or tomorrow date what lands, any other name tags what lands.
- Kanban (three adjacent regions), a pipeline (N in a row), an inbox (a pinned lens that makes tasks).
- A pinned lens: a live query kept on the canvas as a frosted plate of rows (lens).
Don't use it for
- Grouping chrome, cards in a settings page or a list. It is a canvas object.
- A container that owns its blocks: blocks sit in it by position only, and dragging them out undoes the rule unless the rule says otherwise.
