Thanks. And Yes it was made using Streamlit.
Many of the components you are requesting are not there yet. But they are on the list of feature request on Github. Then it’s up to Streamlit.io and the community to take Streamlit to the next level.
But my take is that Streamlit could be very, very powerful to build apps in because it’s so simple to use, powered by Python and really, really fast.
But it needs more layout, formatting and component options.
I will definitely test the limits of Streamlit for developing apps.
