glerikud,@jeffige I apologize as this is really hard to explain so I will go into more detail before I answer the first question you asked. You see I have a title screen. This title screen is supposed to be in a window size of 854 x 480. This fits the game name, a start, and quit button. Now the next level I do not want it to be that zoomed in and want to make the level bigger (I want to see more white space) then the title screen. So I changed the window size and it changed it for every single layout. When I try changing layout size I only see a difference in the Construct 2 editor, not in the actual browser.
I want the window to be smaller in some and I want it bigger in others. Here is an example picture. I changed the layout size like you said. That is what I want it to look like exactly. But you see that dotted line? It goes down past the grey and when you run the game all that grey will go to white and show the entire thing until the end of the dotted line. But in some of my other levels the window size has to be like that in order to see certain things.
