# Objective It is currently hard to configure the `WindowPlugin`, as it is added as part of the `DefaultPlugins`. Ideally this should not be difficult. ## Solution Remove the configuration from the plugin itself and put it as a `Resource`, similar to how it is done for almost all other plugins. ## Migration Guide If you are currently configuring the behavior of the `WindowPlugin`, by constructing it manually, then you will need to instead create add the `WindowSettings` as a resource.
