Installation

Unreal Engine’s Application Scale enlarges the entire editor at once, so every panel, toolbar and margin grows and you quickly run out of screen space. Panel Scaler was built for developers with low vision, or anyone who finds some panels hard to read: scale only the panels you actually read, and keep the rest of the editor as it is.

Application Scale 1.5: every panel, toolbar and margin grows, and the viewport gets smaller.

Panel Scaler: Application Scale stays at 1.0, and only the chosen panels (Outliner, Details, …) are at 1.5.
