It is among our most upvoted feature requests! It is under consideration. Inline output has proven to be a pretty divisive feature; a sizable proportion of users don't like input output at all and consider it a misfeature in RStudio. See e.g. https://github.com/rstudio/rstudio/issues/5280
Out of curiosity, do you prefer source or visual mode when working with inline Quarto output?
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. :)
Inline plots are pretty challenging, especially in source mode since (so far) Positron mostly lets the Monaco editor surface do its thing. In visual mode, we've already got our own custom webview so there's an easier onramp.
