Yeah, we used to only have a the save/as options, but a common mistake was saving as an image like .PNG for example, and forgetting to switch back to .krz and keep saving as PNG thinking you are saving a project even with the status bar message, then closing Karaz and losing all your progress besides the PNG,.
So we kept save exclusive to projects and added export for images, plus it’s much more convenient to have both without going back and forth between projects and images.
