  • Assets & Folders
  • ScriptableObject containers
  • Executable Editor actions
  • Copied text and URLs (paste directly with Ctrl+V / ⌘V)

⚡Work Faster


  • Quick Peek — Hover over the left or right edge of any item to instantly preview it in a floating Inspector.
  • Quick Browse — Press Alt+W (Windows/Linux) or ⌥W (macOS) to open a floating search window from anywhere in the Editor.
  • Scene Linking — Automatically switch to a Base whenever its linked scene is opened.
  • Smart Enter Actions — Press Return or double-click to open Scenes, Prefabs, URLs, inspect GameObjects and Components, or automatically open their scene and focus the object.

✨Organize Your Way

Second Brain uses a simple three-level hierarchy: Profiles → Bases → Containers


  • Profiles — Personal workspaces stored per device. Each team member can maintain their own independent hierarchy.
  • Bases — The root of a hierarchy. Create multiple workspace trees within a single Profile.
  • Containers — Flexible groups that can contain assets, objects, or nested Containers.

🛠Customize Your Workspace


  • Visual Styling — Personalize items with emojis, Unity icons, labels, gradients, font colors, colored dots, and background colors.
  • Customizable Settings — Adjust creation workflow, row height, double-click behavior, and many other editor preferences.
