How to use

1. Create a room — use the Rectangle tab for a quick room, or Draw to click-place vertices for any shape. Close the polygon by clicking the first vertex.
2. Add furniture — click any item in the Furniture catalog. Drag it to position, use the edge handles to resize, or press R to rotate.
3. Doors & windows — arm + Door or + Window, then click on a wall. Click the placed opening to select and adjust it; drag to reposition it.
4. Save your work — export the layout as JSON via Export / Import, and reload it later with Import.
