The quick navigation and action bar is available on all pages, however the content differs depending on the module displayed.
The left part of the bar will allow for quick access to modules in the same category as the one currently open with categories being:
Onboarding
Builder
Monitoring
Marketplace
The right part will contain action possible within the module such as export data, create a new object, edit an existing object or delete an object. Each possible option will be detailed in the dedicated module user guide page.
