Users of the Complete edition can now view the structure of an AXAML file in the Document Outline Window. It includes full search capabilities, and clicking an item highlights it in the editor.

Toolbox

Users of the Complete edition will now see the Toolbox populated with controls from the Avalonia framework, any referenced packages or projects, and any controls defined in the project.

These items can be dragged onto the editor window. Support for dragging from the Toolbox to other locations will be coming in a future update.
