Width of the application

[fswan]

I use the windows version marktext with 27' 4K monitor.

After I open a markdown file, It often use part of screen, and most of the screen is blank, I had to scroll up and down when I look a long article. I thins it should display base on the requirement, such as: screen width, size of paper(A3 A4 ...), or customer can design the width, or I can split the screen to multi-page.
