Roll20 Forground Layer

Roll20 Now has the "Foreground" layer feature, allowing for things like roofs, overhanging trees etc, to fade in or out. Roofs to dissapear when you step into a building etc. Dungeon Alchemist could implement a way to allow this automatically, similarly to how the API script correctly imports lightning, windows, doors. This would be a great change for those using the roll20 VTT
