Something that could make creating custom quest logs easier
Example: A way to check active quests and display them in a widget, hiding them when inactive and showing them when active.

Adding on to this, something similar to

if player.property["Quest_Example"]== true then
display.text["Custom_Quest_Widget"] id["0001"] ["${quest["QUEST_0001"].name}: ${quest["QUEST_0001"].description}"]
end;

Or something similar.
