To set preferences for QML Language Server, go to Preferences > Language Client > General and select QML Language Server.

## Turn off QML Language Server for all projects

For more information about how to turn on and off language servers for a particular project, see Configure language servers for projects.

## Use advanced features

By default, QML Language Server issues warning messages and provides code completion, while the embedded code model handles advanced features, such as renaming symbols and finding usages.
