also (from the docs):

> Ghostty supports the Kitty graphics protocol, light/dark mode notifications, hyperlinks, and more. This lets terminal applications like Neovim, Zellij, and others do more than they could in other terminal emulators.

Application features are higher-level features that are useful for interacting with the terminal emulator itself. For example, Ghostty supports native tabs, splits, a drop-down terminal on macOS, theme switching on system dark/light mode, etc.
