Multi-layer file formats

[IcedQuinn]

It would be nice to support a format like TIFF.

I recently did sprite work for a game where the sprite must be kept across many layers. Exporting this requires painfully going to each layer and doing a manual export for each one. There are also tools like Pixel Composer which can read layer data (from Aseprite) and use that, or other tools that could pop open the TIFF files while keeping layers intact.
