Setting paper width in composition mode

I don’t see a way of changing the default starting paper width in composition mode unless I really miss the part of the manual that explains it. Every time I open the composition mode, I need to go down to the slider and enlarge the width. It’s a bit annoying. Is there a way of setting it up in the Preferences? I don’t see it. If not, it’d be great to have it as an option

After setting the paper width as you want it in a project, open the Preferences and, in the “Compose” pane, click on “Use current composition settings for new project”.

Hope that helps.

All the best,
