Would it be possible to have a layer manager?
It does! Unless I'm misunderstanding. You can import multiple layers and edit the order they render in using the eye-icon on the inspector. Is there more functionality you'd like out of it? I definitely need to showcase it better on the itch page.
One feature I was hoping to add, is the ability to see a list of the layers. So you can select them via list instead of clicking directly. Is that what you meant?
I found a workaround on the layers, because 5 is not enough for me:
You can number your art to show up in a certain order. But it definetly would be much easier for the user to simply create layers and have a drag & drop to rearrange the order or the files instead of ordering them alphabetically, because its not that easy to fix if you made a mistake naming them.
