Folders — Folders, not separate workspaces

Your account has one home for its data, and everything in it can relate to everything else. Folders are how you organise inside it — Sales, Ops, one per client — and they are deliberately not walls: a Deals table in one folder can link to a Companies table in another, follow lookups across it, and roll values up through it. That is the whole reason folders replaced separate workspaces. Every boundary between workspaces is a place where relationships stop, and relationships are the point. Tables in different folders can still be linked, rolled up and reported on together — a folder is a drawer, not a wall.
