I prefer source mode when building Quarto files in RStudio.

Thanks for listing this feature request... It's pretty shocking to me to see that so many people don't use inline plots! I am particularly fond of them for ensuring that plot dimensions are correct so that I don't need to resize everything once I render a report and add it to my Quarto website.

From curiosity on my end - are inline plots a technically challenging problem? I have no idea if VSCode would enable something like this out of the box. :)
