wishlist items

I don't have labeling abilities on this repo, but am listing here to flag to discuss for next knitr release 👋

1. Way to show chunk options in output more easily (see Option to show chunk options in output #1688, see also Feature request: rmarkdown verbatim chunk / inline ThinkR-open/remedy#61 and https://community.rstudio.com/t/question-feature-request-code-chunk-option-verbatim-true/33521)
2. Make the progress bar more compact (see Rethink the progress bar #1880)
3. Ability to include a file (see include_file #1275)
4. Use the chunk label as ID in HTML output (see Use the chunk label as an id in the div of class figure when inserting image #1956)- we should discuss how this will be handled in the future too
5. Something like knit_pause() (see Feature request: knit_pause() #1774)- wonder if knit_exit() could still be used, but there could be a programmatic way to later in the doc turn re-enter? Like knit_enter() or knit_exit(cancel = TRUE)?

I see @cderv collated 2 of these also in issue #1931
