To explain what I'm attempting to do, I'm designing a linear visual novel with the RPG Maker MV engine. I had started this project before the Visual Novel Maker had came out, and I'm comfortable enough with MV that if possible, I'd like to continue working with it. I'd also hate to start from scratch when I have the menu almost exactly the way I'd like it, but please feel free to give your advice on the VNM vs MV matter.
But onto my problems!
I would like to allow players to toggle auto-advancing dialog. Excuse me for this example, as this is the only Visual Novel I've played, but much like how Doki Doki Literature Club has a clickable "auto" option, that is what I would like to use for mine. The ultimate goal is to make the game, if desired, an experience one can just sit and watch at their own pace instead of having to be glued to the Enter key to advanced dialog. I have YEP'S Picture Common Events (or Galv ScreenButtons) that I had intended to use to create this feature, but I'm unsure how to go about it.
When I pause the game during a Show Picture command, it erases the image; it also resets text back to the beginning of the paragraph. That one's pretty straight-forward, but I'd like to essentially pause/freeze the game in place and not have pictures disappearing or dialog resetting.
BONUS. Moreso an aesthetic issue, I'd like to remove the text highlight when selecting a choice, since I have put a cursor in its place. Example:

If it would help, here is the list of the plugins I currently use:
