With this feature, you can set props, brushes, shapes, and text as a 'map decoration'.  This will place it above all objects including 'above wall' objects and tokens allowing you to detail and decorate your whatever needs you have.
Object Option:
Map Decoration - Enables/Disables this feature for the selected object.  Enabling this feature will disable the option 'above walls' as a map decoration appears above all objects.
Map decoration properties
Objects with active map decoration flag will:
- always be rendered on top
 - are not affected by dynamic lighting (ambient, light sources & shadows)
 - are not being displayed in player views
 - you can toggle their visibility on export via the export view options
 
Export Option:
Show Map Decorations
 - This new export feature allows you quickly hide or show map 
decorations so you don't have to manually hide/unhide them before making
 a second export of your map.
