Hello.
I realize that the Construction Set probably doesn't have a default checkbox-type option, nor is it likely an option in Tweeks, though while the silent dialogues don't bother me, I think that it should wait for me to push a button before the NPC continues from one comment to the next. That might require a lot more scripting, like customizing the dialogue scripts for each Topic & Quest in the game, though I think that would be worthwhile work & could really facilitate new Quests being made & implemented, optionally, into MorrOblivion.
I'm only guessing that there's a Script function that allows for the dialogue to wait until the player pushes a button, if aside of inserting extra steps in between each comment where the player pushes a button for the NPC to "Continue...", though I'm an avid reader & the NPC dialogues progress faster than I can keep up, even if I'm trying to read really fast sometimes. I actually think that I would be less irritated of the dialogue if I were reading it au lieu listening to some voice actor.
Anyway, I think it would be helpful work, & I wanted some response about impressions the other Community members might have about that sort of Mod work.
Thanks.

Hi, there are already mods
Hi, there are already mods that let you press a key for the dialogue to continue. There are also mods that introduce silent pauses as well as produce spoken words. Please have a look on Nexus or even search this site for more info.
