Mod to mark important NPC?

Is there a mod that marks which NPC are important to talk to or at least have some level of dialogue options? I ask because in act 3, the city is riddled with not only non-interactive NPC, but all these “flavor” npc that literally only have one line. I like the realism and bits of lore they give, but it’s draining to talk to every guard and cook to find the 1% with important information. Some kind of color outline or marker when you hover over them would be really helpful.
