📣 Introducing Dash `/pages` - A Dash 2.x Feature Preview

Hi @snowde

I haven’t made a multi-page app using flask and multiple apps so I can’t speak to the pros and cons. (If someone else has, please chime in).

However, this is from the Dash 2.0 announcement:

@dash.callback will not work if your project has multiple app declarations. Some members of the community have used this pattern to create multi-page apps instead of the official dcc.Location multi-page app solution.. The multi-app pattern was never officially documented or supported by our team.
