The flow editor

The editor has the block list on the left, the canvas in the middle, a block's settings on the right when one is selected, and Ask xMap at the bottom.

• Add a block: drag it from the list, click it to add it after the selected block, or press + on a selected block for the four blocks that usually come next.
• Link two blocks by dragging from the dot on the right of one to the next. Select a link and press its + to put a block between the two.
• The sentence above the canvas says what the flow does. Click a part to open its block; some parts (the schedule, the cities, the type of place, the email address) can be changed right there.
• Move around by dragging the background, zoom with the buttons or the wheel. On a phone, pinch and drag.
• History shows earlier versions of the flow; any can be restored.
• Comments are for the team: type @ to mention someone.
• Draw: the brush, first in the bar at the bottom right, opens the drawing tools (notes, text, shapes, arrows, pen, marker, sections, stamps, eraser). Click a drawing to change its colour, fill, thickness and more. A section carries the blocks inside it when moved, an arrow dropped on a block follows it, and Label this flow titles each stage for you. Drawings never run and cost nothing.
• Live estimates: a block that finds or filters things says, a second after you change its settings, about how many it would pass on, for example about 120 coffee shops on Nearby places or about 45 left on a Filter. They are worked out on sample data in your browser, so nothing is searched and no credits are used; a run shows the real numbers in their place until your next change. On a phone they show in the list of steps.

Watch a block's film without leaving the editor. A block that has a short film (about a minute) says Watch how it works under its description in its settings, and shows a play button when you point at it in the block list. The film plays in a small window over the editor, with its narration and captions; close it and you are back where you were. App blocks and app events play the film of all app blocks, drawn with that app.
