Rooms are made up of objects called 'Widgets'. Widgets can be added, moved, edited, and removed to customize the room.
Add widgets by clicking on them in the toolbox at the bottom.
Drag widgets to move them where you'd like.
Some widget types have additional options that can be changed. Click the widget to open the menu with options.
For more information about individual widget types, visit the main docs page.
To remove a widget, click it and select Remove from the menu.
