Great idea. Happy to test.

Found this small issue that \r is not recognised. So any status or progress bar in text (that rely on \r) don't display correctly.

cat("hello\r123\n") hello|123 # as seen in RStudio, not correct

cat("hello\r123\n") 123lo # correct

   Thanks for letting us know! Is this a common thing in R packages?

   NP. RStudio looks very nice.

   txtProgressBar() in utils relies on \r. It's quite useful to see a progress %, or bar, on one line at the console, for example. I don't know how many packages or users use txtProgressBar() or \r directly but I guess it's quite common.
