 15. **install-local.ps1 dependency list**: The local install script has a hardcoded `$Dependencies` array listing DLLs to copy from the `publish/` directory. When adding new NuGet packages (e.g., Spectre.Console), you MUST add the DLL to this list or the module will fail at runtime with assembly-not-found errors. Consider replacing this with a bulk copy approach (like `install-remote.ps1` does) to avoid this pitfall.
 16. **PCD interactive selector excludes current dir and `..`**: `PcdInteractiveSelector` explicitly filters out the current directory and the `..` parent shortcut. This is intentional — navigating to where you already are is useless, and `..` is always available via `pcd ..` directly. When testing, ensure the learned paths are not just the current directory or its parent.
 17. **FeedbackProvider uses PowerShell `$PWD` for path normalization**: The `FeedbackProvider` uses the PowerShell `$PWD` variable (not `System.Environment.CurrentDirectory`) to get the current working directory for path normalization. This is important because `Set-Location` in PowerShell does not update the process CWD. Always use `PSCmdlet.SessionState.Path.CurrentLocation` or invoke `$PWD` via PowerShell when you need the true PowerShell working directory.
+18. **Navigation timestamp tracking**: For navigation commands (cd, Set-Location, sl, chdir), the FeedbackProvider records the absolute destination path (from context.CurrentLocation after navigation) with trailing separator, not the relative path typed. The `pcd` function manually records navigations under the 'cd' command since FeedbackProvider only sees the 'pcd' command, not the internal Set-Location calls. Without this, pcd navigations wouldn't update learned directory timestamps.

 Features:
-- **Visual menu**: Arrow keys to navigate, type to search/filter, Enter to select
-- **Cancel options**: Select "< Cancel >" (first item in list) or press Esc to exit without navigating
-- **Usage statistics**: Shows visit count and last used time for each directory
-- **Smart filtering**: Only shows directories that still exist on disk; excludes current directory and `..` parent shortcut
-- **Frecency sorting**: Same scoring as tab completion (frequency + recency + distance)
+- **Interactive menu**: Arrow keys to navigate, type to search, Enter to select, Esc to cancel
+- **Visual polish**: Color-coded usage indicators and timestamps for easy scanning
+- **Smart filtering**: Only shows existing directories, same frecency scoring as tab completion
 - **Configurable**: Show 5-100 entries with `-Top` parameter
