Is there a plugin built based on zooming in onto the MC via world map?

That way, the entire map isn't shown, and the camera is more fixed on the MC and party members. Just an idea is all, and I checked on yanfly plugins, and the only camera focused I found is for the battle animations

Use SRD (SumRndmDde's) Camera Control Plugin. That seems like it should do what you're looking for.
