"Skip to input": Hold a button and automatically advance through a scene to the point where you get to make an input(excluding skips). This would save sooooo many clicks for people that do lots of playthroughs. If it's too late or somehow impractical to add into BG3's dialogue system, it would be nice to see in Larian's next game.
"Refresh options": If we could manually refresh dialogue options, we would be able to be rid of the "expired" dialogue options and possibly the "Continue." bug as well, since updating dialogue would remove inaccessible and add accessible choices.
