The window

The window has three areas:

Sidebar: All assets, Favourites, and your categories. Each entry shows its asset count.
Asset browser: the grid or list of assets in the current view.
Inspector: the selected asset, its normal Unity inspector, and any Editor Pro extensions.

When nothing is selected, the inspector area shows a small overview of the current category: asset count, type count, most common type, and a type distribution.

Hover an asset to see its name, type, and path. In All assets, an unassigned asset also shows that it is uncategorized.

Finding assets

Use the search field at the top of the browser. It looks through:

Asset names
Type names and full type names
Extra terms supplied by a registered search provider

Use the sort/filter button beside search to:

Sort by Type, then name or Name A-Z
Search the available asset types
Choose one or more types to show
Clear the selected type filters

The view can be a Grid or List. Change it in Settings. Grid cell size is also set there, from 72 to 156 pixels. Drag the divider between the browser and inspector to give either area more room.

The refresh button asks Unity to refresh and rebuilds Editor Pro's asset list. Use it after a larger project change if the normal automatic refresh has not caught up yet.

Creating assets

Click the + button, search for a type, then choose it. Editor Pro asks where to save the new .asset file and opens it when it is made.

The create menu only shows enabled, non-Other types. Recently used types appear first, followed by types with a higher registered creation priority and types that are already used in the current category.

For each type, Editor Pro first tries that type's normal Unity Assets/Create command. If there is no command, it creates the ScriptableObject directly. Integrations can replace or add to this workflow; see Creation API.

Selecting assets and tabs

Click an asset to open it in the inspector.

Click: open one asset and replace the current open selection.
Ctrl-click on Windows/Linux or Cmd-click on macOS: keep the current assets open and add this one as another tab.
Shift-click: open every visible asset between the first selected asset and this asset.
Click a tab: make that asset active in the inspector.
Click the x on a tab: close it. If it was active, the tab before it becomes active when available.
Double-click a tab: Editor Pro switches to that asset's category and scrolls the asset into view in the browser.
Double-click an asset in the grid or list: Unity pings that asset in the Project browser.

Open tabs are on by default and can be turned off in Settings. When there are many tabs, use the horizontal tab bar to move through them. Editor Pro restores open tabs, the active asset, the selected category, search text, view, sort choice, pane size, and scroll positions when the window is reopened.

The lock button keeps the current inspector visible while you browse or open other assets. The other assets can still be added to tabs; they simply do not replace the locked inspector.

Working with an asset

The inspector header lets you:

Rename the asset by editing its name. This renames the asset file in Unity.
Duplicate it. The copy is made beside the original as Name Copy.asset and opens in a new tab.
Delete it after confirmation.
Add or remove it from Favourites.
Ping it in Unity's Project browser.

Right-click an asset in the grid or list for the same actions plus Move / Rename, which opens Unity's save panel. The menu may also contain actions supplied by an integration.

If a normal inspector field references another enabled ScriptableObject, clicking that reference opens the referenced asset in a new tab. Clicking the small object-picker button does not do this.

Categories and favourites

Every asset gets its category from its type unless you assign the asset itself to another category. This means you can put most Quest assets in Quests, then move one special quest somewhere else without changing the type's default.

To move assets, drag an asset from the grid or list onto a sidebar category. Dragging onto Favourites adds it to favourites. If the dragged asset is one of several open assets, Editor Pro drags all currently open assets together, which makes batch moves quick.

Uncategorized and Other are built-in categories. They appear in the sidebar only when they have assets. They cannot be removed. If you delete a custom category, its types and any asset-specific assignments move back to Uncategorized.

Sub-categories

Categories can be arranged in a hierarchy. A parent category shows the assets assigned to it directly, as well as the assets in all of its sub-categories.

The onboarding screen has a Categories panel on the left. Use it to add, edit, and arrange categories before you start browsing. It works the same way as the Categories section in Settings. The category picker for each asset type also shows sub-categories indented below their parents.

Create a sub-category

Open Categories in Settings or on the onboarding screen.
Enter a name and select Add.
Drag the new category onto the category that should be its parent.

Use a category's drag handle to rearrange existing categories.

Browse categories

Select a parent category to expand or collapse its sub-categories. Selecting the parent shows assets from the whole category hierarchy. Selecting a sub-category shows only its own assets and the assets in its sub-categories.

Move categories

Use the drag handle in Settings or onboarding:

Drop in the middle of a category row to make the category a sub-category of that row.
Drop near the top or bottom of a row to place the category beside it.
Drop near the left edge of a row to move the category to the top level.

When you place a category beside one with a different parent, it moves under that parent. Editor Pro ignores moves that would make a category its own parent, directly or indirectly.

Category icons

When you edit a category, Use icon is on by default. Turn it off to hide the icon and give the category name more room in the sidebar.

Settings

Open Settings with the gear button. It opens as a tab and contains:

Layout

Switch between Grid and List.
Set grid cell size.
Show or hide open tabs.
Reset the layout to the default grid, default cell size, visible tabs, and default pane width.

Asset browser

Use Exclude folder to hide a folder under Assets and everything below it. This is useful for generated assets or content you do not manage by hand. Excluded assets are removed from the browser and from open tabs. The root Assets folder itself cannot be excluded.

Maintenance

Configure asset types returns to the welcome/type setup screen.
Reset Editor Pro clears Editor Pro categories, type choices, favourites, create history, tabs, and saved layout. It does not delete your Unity assets.

Editor Pro also checks for package updates. An available update can be closed, skipped for that version, or opened in the changelog.

Built-in integration

When Game Creator 2 is installed, Editor Pro automatically tries to use its item, shooter, stats, quest, melee, and related sprites as asset icons. No setup is needed. If an icon cannot be read, Editor Pro falls back to Unity's normal type or asset icon.
