No, its not that. What I mean is, whenever I wanna save a file with multiple layers, it defaults to "save as" pdn. I wish it would default as png, without needing to first merge the layers and then save it.
I use paint.net to create textures for game development and every time I wanna save, I need to undo the layer merge and change the "save as" file from pdn to png. Is there a way or a plugin that avoids these steps? Thanks.
