First, please be careful with the indentation. It should always follow the pattern used in the file (spaces or tabs) - you don't need to fix any indentation from others, but the new code should always be indented properly.

Second, when you add a new option such as priorityRatio, you should include that option in the config.xml.template (https://github.com/jtpastro/bigbluebutton/blob/new-videodock/bigbluebutton-client/resources/config.xml.template#L56), so others don't need to look into the code to be aware of a given module options - they just need to check the config template.
