Here's an example: https://youtu.be/ooo51ZRgU_4?t=351
I want to be able to just save the image on the right which will update the picture on the left. This could be done with smart objects I guess, but that's not the case in the Jazza's video. I'm baffled.
I know there are some other solutions, but I want it to work just like in the video. Pressing save updates the image on the left.
For those looking for similar solutions: Pyxel Edit has similar kind of functionality and it's the best.
