# UI settings

Most features require some configuration in the form of settings that need to be specified for each applicable server on which the feature is expected to work. When using or combining solutions using the default settings with their default server keys, no changes are required.

If you are using different server keys or want to alter settings, you can do so via the solution’s `activate` function by overriding the `settings` parameter.
