How can I disable the launcher bar in my Finsemble application?
The launcher toolbar is disabled by removing its definition from component configuration. In the seed repo you will need to modify your component config. During the tutorial you will have moved the sample toolbar into a folder and migrated the config as well. If you remove the "Toolbar" property from that file, the toolbar will no longer show up.
