Yeah, I'm still figuring out all the RPGMaker mechanics and plugins and how they all work. That specific option might be locked behind a paid plugin, but I'm definitely looking into it for the future.
I am trying to make future maps more compact. Maybe I'll go back and make some of the maps smaller and more compact. But at the very least I can go back and add map markers. (there are stones in front of side doors, but yeah I can make it easier than that).
