Quick Level Manager for Unreal Engine

Quick Level Manager is a small Unreal Engine 5 editor plugin that puts a level switcher in the Level Editor toolbar. You keep a list of the levels you actually work in, and open any of them in one click instead of going through the Content Browser.

I made it because on a project with a few hundred maps, opening a level is a search box and a scroll, every time, all day. The levels you actually open are usually the same five.

What it does

• Adds a dropdown to the toolbar, right of the play controls, listing the levels you chose.
• Opens a level in one click, with the same save prompt you get from File > Open Level, so backing out of it cancels the switch rather than losing work.
• Keeps the list in Project Settings, written to a config file you can commit, so a team shares one list instead of each person building their own.
• Disables itself during Play In Editor, because loading a map mid-session would tear the session down underneath you.

How it is built

• UE 5 C++ editor plugin. Two classes, about two hundred lines, in an Editor module so it is compiled out of packaged builds.
• The button extends LevelEditor.LevelEditorToolBar.User, the engine's own toolbar extension point.
• No custom Slate style set. It borrows AssetEditorToolbar and the LevelEditor.Tabs.Levels icon, so spacing, hover states, theming and the icon only layout all come from the editor.
• The level list is a UDeveloperSettings of soft object references to worlds, which is what produces the asset picker rows in Project Settings. defaultconfig puts it in a committable project ini.
• Opening a level reuses File > Open Recent's path: SaveDirtyPackages, stop if cancelled, then LoadMap.
• The menu is built from a FNewToolMenuDelegate, so it rebuilds on open and settings changes appear immediately.
