unlikely to provide a very good django CMS editing experience. Older devices will often lack the performance to support a usefully responsive frontend editing/administration interface. The following devices managing django CMS in the browser’s private (also known as incognito) mode can have significant performance implications. This is because local storage is not available in this mode, and user state must class Level(Modifier): """ marks all node levels Performance issues in menu modifiers Navigation modifiers can quickly become a performance bottleneck. Each modifier is called multiple times: For
