A little update on what I'm currently coding; I started to design different modes for the editor, the next update will bring two of them and maybe a third secret one
Advanced mode :
This will be the generator as you all know know it for now, with its complex options. But with that, you can define any kind of template, and so on. Perfect for people who don't want to use the default format of RPG Maker.
Default MV mode :
This mode "simplifies" a bit the editor, where you don't need to consider the templates, categories, anymore. Instead, you'll use the templates of RPG Maker MV. Of course, you can still add new colors (mask are not a bother anymore here), and shift elements, add many facial marks at once, and so on. I'm starting to design an easier window for adding new resources on this mode. This is the current state of the window, far from complete for now, of course.
Others modes :
This will come later, if people ask me for different modes, let's say RPG Maker XP, I'll add them. Completely new things might also come, depending on the demand. These kind of modes may also contain default resources, as long as redistribution is authorized and the resources are copyrighted.
Meanwhile, I started adding a few things. The elf ears will be correctly imported in the next version, and the resource window can now be resized, as it was asked some time ago.
This is it for the current state of the generator. I hope I'll be able to release v0.08 quite soon for you guys to use the new functionalities

Don't forget to check the front post, as I'm updating in there the current changes and suggestions.
