hyprland-wiki/pages/Configuring/Master-Layout.md

The master layout makes one window be the "master", taking the left part of the screen, and tiles the rest on the right.

Quirks

The right, "slave" windows will always be split uniformly. You cannot change their size.

However, you can resize the master window.
