I have. The problem is there's no easy, obvious way to do this in RPGMaker. Most game devs just have a "room" with buttons you interact with to pull up each of the scenes, but I've been holding out for a while because I want an actual GALLERY, which is...harder to do than you might think. I'd also like it to be accessible from the main title screen, which again, not immediately easy to do with default RPGMaker. But, it is under consideration, and hopefully I'll be able to find/put together a system for it eventually. In the meantime though, there is a guide under the Sceneguide/Flowchart wiki that'll help you double-check at a glance if you have everything. It hasn't been updated to this latest pack yet, but should be before too long.
