Sometimes the image I save in this repl goes into its own window so I can see it update when the image changes; same with the csv file. However this is not always the case and there does not seem to be a repeatable way to trigger it.
Edit: there is an example of what this looks like in this blog post: https://repl.it/site/blog/ide
I think it is triggered when an image is either uploaded or changed. Although I'm not really sure. I had thought they removed that feature.
