So, I've noticed with the countless of hours playing recroom that there sadly isn't a way to add custom GUI elements. I'm currently working on a game called "WinterHaven" where the user is prompted to join new rooms with a 3D prompt. It'd be really nice, as a creator, to be able to create onscreen dialog with characters. Perhaps this could be done by making a custom ui development tool for the watch. But if this would ever be a thing, I'd suggest that when the GUI is triggered, that the player gets a notification that would open this feature. I would need the ability to create buttons, as well as images (Perhaps recroom images). I truly think this could help a lot of developers in this vast community.
An example of what I would want to create:
