.inientries ;the same format used by the built-in database. Custom Cleaners integrate seamlessly into the existing cleaner architecture. entries behave identically to built-in ones and feel like a natural part of the app rather than a bolted-on feature - Write PowerShell
.ps1scripts as first-class cleaner entries - Built-in editor with load template shortcut for both formats
- Run
.ps1scripts directly from the list with live output streamed to the header - First
#comment line of a script is used as its description - Full-text search across names, types, and descriptions
