Builder

The course's screens as a slide-sorter, imported from the builder. Drag a tile to reorder, hover for duplicate / delete, click to open it in the editor below, or use the trailing tile to add.

The full-screen phone editor from the builder. Scroll the feed to move between screens (selection follows the centered phone), edit the centered screen inline, and add screens from the seams or the ghost phone at the end.

Without onDuplicate / onDelete / onAdd, the strip becomes a static, reorderable gallery — useful for previews and summaries.
