Improve Layout Width for 2K / 4K Displays

[ykla]

I would like to request that GitBook provide an option to increase the content width for high-resolution screens such as 2K and 4K displays.

Currently, the main content area is extremely narrow on larger monitors—often occupying less than one-third of the available screen space. This results in inefficient use of display area and forces unnecessary scrolling, especially for technical documentation, code samples, and long-form reading.

Adding a setting or responsive layout mode that allows wider content rendering on large screens would greatly enhance readability, improve visual balance, and provide a more modern documentation experience for users working on high-resolution displays.

Thank you for considering this improvement.
