Bars

• Added a public beta of our new Bars product, which implements advanced fluent ribbons, toolbars, menus, and related controls.
• The Ribbon control has the latest Office appearance and includes the use of subtle animations throughout all controls.
• Ribbon can instantly switch between Classic (taller) and Simplified (single-row) layout modes, allowing for configuration of the variant resizing behavior in both modes.
• Complex galleries can appear in the Ribbon, as well as in any popup and context menu. It's simple to create new galleries with rich visualizations for any need.
• The StandaloneToolBar control can be used as an app's primary toolbar, or alternatively within tool windows. It can host any control that can be used in Ribbon and overflows items to a popup as needed.
• Controls inherit similar native Avalonia controls wherever possible.
• UI accessbility peers are implemented for the entire control hierarchy.
• The entire control hierarchy can be built using MVVM (preferred), or alternatively directly in XAML.
