You might notice a smidge of extra visual activity happening down in the Pen Editor footer lately. We're trying to show you a bit more information about what the Pen Editor is actually doing.
Here's an example (5 second video) where I'm editing some HTML to include an
<em> tag or not, and the editor is doing stuff to make that happen for me:
The idea is to show you (and us!) what is happening in the Pen Editor as we do it. Like sometimes code needs to get processed. Sometimes the preview needs to get rebuilt. Sometimes your code is off being linted or formatted. There is a bunch of stuff that might be going on in the editor, and we wanted a dedicated place to be clear about that rather than having it be a silent mystery.
