Thanks! Really an excellent tool! I'd originally written a shiny app, but this was much better!

Other than the plot (thanks, gballan), it would be nice to adjust the width of layout cells, especially for the code cells. It would also be cool to adjust the spacing between cells to reduce whitespace when another cell in the same row takes up a huge amount but others do not.

I was not clear how to place markdown text in between or after tables and sliders but might have just missed how to do that.

Thanks again!
