If you navigate from dashboard to dashboard within the app, you’ll stay in kiosk mode.
Are you referring to loading SharpTools.io in an iframe to build a custom navigation like you mentioned in your other posts? If so, each time you change the URL of an iframe, it’s basically like loading a page from scratch, so it’s completely reloading the app which briefly shows the navigation.
Let me see if I can come up with an API that can be used for cross-window communication so you can change the route without having to change the iframe URL which loads a new page.
