The original idea was to add an option to play the old "writing" sound back from vanilla when quests were written word by word.

After having been playing the latest Zelda game lately, I think this option should enable dialog "sounds". We could choose a few sounds for the game's model if we can find them, like "hmm", "ugh", "ahh" and have them play during the dialogs. Then when there is no NPC model the writing sound would be chosen.

Old writing sounds path:

Sound/Interface/WriteQuestA
Sound/Interface/WriteQuestB
Sound/Interface/WriteQuestC
