RStudio IDE supports inline/tool mathjax equation previews of equations using $ or $$ syntax for RMarkdown documents, e.g.

```
a^2+b^2=c^2
```

However, if I want numbered labeled equations in bookdown I need to use LaTeX `equation`

syntax

```
\begin{equation}
a^2+b^2=c^2 \label{eq:pythagoras}
\end{equation}
```

(Typically actually `\begin{align}`

)

These are not, AFAICT, previewable. This is vexing because it is precisely these equations which are likely to be complex enough to need preview.

Is this feature on the RStudio roadmap? Or is it perhaps already in there and I just haven't noticed where?
