A profile name. Displayed in the extension and console.
A profile description. Displayed in the extension and console.
A template directory. If specified, all contents of the provided template directory will be copied to a newly-created profile. This is useful if you want to create a new profile with the same extensions, settings, etc. as an existing one.
This is not a real property. It only exists when creating a new profile and cannot be changed afterward, as copying from a template is a one-time operation.
