It is possible to use a specific Camel Catalog version. This can be specified in File -> Preferences -> Settings -> Apache Camel Tooling -> Camel catalog version

It is possible to use a specific Runtime provider for the Camel catalog. This can be specified in File -> Preferences -> Settings -> Apache Camel Tooling -> Camel catalog runtime provider
Additional Camel components can be provided. This can be specified in File -> Preferences -> Settings -> Apache Camel Tooling -> Extra-components -> Edit in settings.json
You can add a list of Camel components definition. This json definition can be found in jar of the Camel component. You will end up with something like:
It is possible to use dashed notation in properties file and Camel K modelines. By default, the completion is using the camel cased notation. It is using the dashed notation when there is another Camel property already using dashed notation in the same file.
