Yeah. What I should have added here, but didn't want to sound brash and rude, is that Streamlit should focus on having a reliable working product before spreading out as an org with a Dev Relations department.

I know this is a complicated problem domain (because it's the web, Mathematica did this well with complex graphs in the mid-90s), but as it stands now my project has an input on which the graphic depends and a default value; the image breaks before the input control is touched. And it's not a slider, it's a dropdown that makes the app query a db first... I mean, I think I can do this in plain Ajax if I get my story right about sending images. But it's a hobby project meant to explore mathematical ideas...

If you can't do sliders reliably, they should be moved to a beta branch. Streamlit overpromises and underdelivers. But it's a great project, I don't want to be too negative about it.
