Oh awesome! I actually got Yanfly's Full Collection bundle about a month ago since I already use a good amount of his plugins. However there are so many I haven't had the time to really look through what each one does. Turns out that Item Synthesis one is in there as well. Thanks for letting me know!
Thanks! Map layouts are one of the hardest things for me on Wayfarers. I'd much rather be writing random NPC dialogue and figuring out event commands than do them. Haha.
