Sometimes people miss stuff, especially if they've been using the software for several years.
I personally only discovered a few features in RPG Maker after someone asked a question and I had no idea what they were talking about.
Therefore, I'm trying out an RPG Maker tutorial in the form of a series of "Did you know?" images that provides random bits of information that you may or may not have known about RPG Maker MV!
If you have a tutorial that goes more in-depth into any of these topics, just let me know and I'll include it for further reading/viewing!
Did you know about Hidden Items?
Did you know why there are two Hidden Item categories?
