CompactUE is an Unreal Engine Editor plugin that gives you back the screen space the editor's default layout wastes.
The Unreal Editor stacks multiple horizontal bars on top of each other: a title bar with the menu, an asset tab bar, a toolbar, a viewport toolbar, a viewport, and a status bar at the bottom. On a laptop or a small monitor this adds up fast, especially when you open Asset Editors or the Blueprint Editor, each with their own set of bars. CompactUE merges, relocates, and collapses these elements so the viewport and content areas get significantly more vertical room.
On top of that, CompactUE includes Focus Mode: a single-hotkey toggle that collapses every side panel (Details, Outliner, Content Browser, and others) into sidebars, giving you a clean, distraction-free view of your viewport or graph. Press the key again and everything comes back exactly where it was.
The plugin works entirely through Slate widget manipulation at runtime, no engine source modifications are needed. It targets the Level Editor, Asset Editors (Material, Animation, Niagara, etc.), and the Blueprint Editor.
If you find some editor that the plugin doesn't work on, please let me know! I'll do my best to fix it as soon as possible.
