Thank you Benny! For your proposal consider that I thought about adding extra information when you access the menu, so you would see all the stages highlighting the current one and what things you can and cannot do in that form. It still doesn't have a final look because I have to see if I can make 4 dedicated tabs by changing them with the directional keys or not.
It doesn't show me the images correctly, I would have liked to do a comparison to see what the setup looked like. :)
