Hi @pybokeh
When ever I read your posts I feel like we have so many things in common. 
I would really like to be able to do a multipage app with a better layout. Something like
https://getbootstrap.com/docs/4.3/examples/dashboard/
For this i would need a “navigation” widget with “nav items”. Something like shown in the sidebar of the widget. I would like to use fontawesome icons or similar for the “nav items” (and for my buttons).
I would like a “top” bar and “footer” bar as well.
I would also like some kind of “url” routing such that if I go to the dashboard page “/dashboard/” is appended to the url. And if I go to the “Orders” page “/orders/” is appended. I need this so that my users can bookmark the pages if they normally use a specific one in a (deeply nested) multipage app.
And I would need a grid layout like discussed here https://github.com/streamlit/streamlit/issues/309
