Canvases & the rail

Each canvas is an independent model with its own history, health config and links. The left rail is the explorer: your workspace at the root, canvases inside it, and each canvas's flows nested beneath. Click a canvas to switch, a flow to play it — flows on another canvas switch you there with the flow already running.

• Create a canvas with the + next to the workspace row; delete one from its row menu (the last canvas can't be deleted).
• The Tags tab holds the current canvas's tag definitions and their visibility toggles — see Tags & filtering.
• Collapse the rail with its chevron — the reopen chip sits beside the breadcrumb. The rail remembers your choice.
