-# Feature: 'source edit'
+# New Feature: 'source edit'
 New feature that adds an 'edit' subcommand to the 'source' command. This can be used to set an explicit source to be implicit and vice-versa. For example, with this feature you can make the 'winget-font' source an implicit source instead of explicit source.
 
 To use the feature, try `winget source edit winget-font` to set the Explicit state to the default.
 
+# New Experimental Feature: 'listDetails'
+
+The new experimental feature `listDetails` enables a new option for the `list` command, `--details`.  When supplied, the output is no longer a table view of the results but is instead a series of `show` like outputs drawing data from the installed item.
+
+An example output for a single installed package is:
+```PowerShell
+> wingetdev list Microsoft.VisualStudio.2022.Enterprise --details
+Visual Studio Enterprise 2022 [Microsoft.VisualStudio.2022.Enterprise]
+Version: 17.14.21 (November 2025)
+Publisher: Microsoft Corporation
+Local Identifier: ARP\Machine\X86\875fed29
+Product Code: 875fed29
+Installer Category: exe
+Installed Scope: Machine
+Installed Location: C:\Program Files\Microsoft Visual Studio\2022\Enterprise
+Available Upgrades:
+  winget [17.14.23]
+```
+
+If sixels are enabled and supported by the terminal, an icon for the installed package will be shown.
+
+To enable this feature, add the 'listDetails' experimental feature to your settings.
+```
+"experimentalFeatures": {
+    "listDetails": true

 ## Bug Fixes
 * Portable Packages now use the correct directory separators regardless of which convention is used in the manifest
 * `--suppress-initial-details` now works with `winget configure test`
