The Classic Modifier Menu is an extension that brings back the legacy interface layout for adding modifiers in Blender 4.0 and newer versions. It replaces the native menu system while retaining updated core functionalities like integrated search capabilities. The tool introduces a distinct Add Assets menu specifically for handling the insertion of modifier assets, which can be configured alongside the main menu in the properties panel.

Users can customize how the menus are presented, with options for horizontal or vertical arrangements, dropdowns or buttons, and input modes such as typing to search or using accelerator keys. The interface allows for configurable hotkeys and supports object-specific context, automatically adjusting for mesh objects or Grease Pencil elements.
