The first feature would be to see the list Quarkus apps and be able to:
start dev => open (in browser) | dev-ui (ide) | restart | stop (something should check if the dev-server is up)

Then later it could also:

• give a way to list/add/remove extensions
• check if the versions are up to date / trigger update
• see if the plugin is up to date (update)
• list resources with link to java code
