Hierarchy

A per-screen tree view: one row per object, nested under whatever it's parented to. Right-click empty space to add a new object; right-click an existing one for rename, duplicate, delete, and reparenting.

Common moves

• Add: right-click empty space, pick an object type (Add Text, Add Button, Add Image, and so on. Starter shapes, not raw empty components).
• Reorder / reparent: drag a row onto another to make it a child, or between two rows to reorder siblings. Draw order follows this list, so a later row draws on top of an earlier one.
• Multi-select: Ctrl/Cmd-click or Shift-click a range; Cut/Copy/Paste and most Inspector fields apply to the whole selection at once.
• Eye toggle: hides an object in the Canvas/Preview without deleting it; hiding a parent cascades to its children.
