Hi @EmilHvitfeldt - i'm loving the code windows!

I found a potential bug when using code-line-numbers in a code window. When I specify which lines to highlight the previously highlighted lines do not un-highlight (they still have the same alpha/transparency).

Here's an example qmd. The first chunk with the code window and the second with a regular code block, both with code-line-numbers:

---
title: "check"
format: revealjs
echo: true
revealjs-plugins:
  - codewindow
knitr: true
---

using `code-line-numbers: "|1-5"`

:::{.codewindow width="500px"}
script.r
```{sass eval=FALSE}
#| code-line-numbers: "|1-5"
library(tidyverse)
mtcars %>%
  arrange(desc(modification_time)) %>%
  slice(1) %>%
  pull(mpg)

fs::dir_info(here::here()) %>%
  arrange(desc(modification_time)) %>%
  slice(1) %>%
  pull(path) %>%
  readr::read_csv
```

:::

# regular code block - this works
using `code-line-numbers: "|1-5"`

```{r}
#| eval: false
#| code-line-numbers: "|1-5"
library(tidyverse)
mtcars %>%
  arrange(desc(modification_time)) %>%
  slice(1) %>%
  pull(mpg)

fs::dir_info(here::here()) %>%
  arrange(desc(modification_time)) %>%
  slice(1) %>%
  pull(path) %>%
  readr::read_csv
  
```

Thanks for the extension - This is really awesome!

Please add the juilia (dots) logo for .jl class :) - https://github.com/JuliaLang/julia-logo-graphics/blob/master/images/julia-dots.svg

.nf Nextflow icon request. Thanks.

Awesome package. Quick icon suggestion: I'd love an .Rmd icon 😇

If you try to put more than one thing, like two code blocks or additional text etc. into a codewindow, codewindow will silently drop the additional elements. An easy way around this (that clutters my source code a bit) is to wrap the second element in a fenced div,

Drops the second code block

::: {.codewindow .r}
my-script.R

```r
runif(1)
```

```r
runif(42)
```
:::

Keeps the second code block

::: {.codewindow .r}
my-script.R

::: {.contents}
```r
runif(1)
```

```r
runif(42)
```

Hi, love the package extension!

I am not a Mac user (pretty anti-Apple, actually), and would love a platform-neutral option to use while teaching my R programming students. I've been promoting the use of RStudio, so it would be nice to use the RStudio/posit.cloud tabset (and it seems like you might even have easy access to the folks that produce the tabsets).

Current output (using my custom .scss theme (thanks, also, for the pointers there) and code highlighting .theme file):

(Apologies if Posit already puts out this tabset; I could only recall seeing this in one of your slidecraft 101 decks).

It'd be cool to be able to make multiple tabs (not actually clickable tags, that's a rabbit hole).

It'd be mostly CSS styles and a little markup so that people could specify multiple tabs and maybe even say which one is active (the last one by default).

bash or terminal icon would be fantastic when sharing Linux code snippets.
