After updating Magnolia version in Maven to

<magnoliaVersion>5.4</magnoliaVersion>

Magnolia menu has less items.

Is this as intended? Do we need to manually configure that menu? Should the new Resources app be visible at least?

Additionally we have moved resources in our custom app jars to the new path "src/main/resources/<module-name>/resources/something.xyz" but they are not being picked up, so we think we must do something more to migrate to 5.4 but we could not find anything in the documentation. Please could you help or refer us to correct project for help?
