This a great idea.

You could also add a collapse toggle ">" to the classname line that will open the focus view (instead of the keyboard toggle). I think the VSCode API supports it.

Thank you for this idea! VSCode API definitely allows to do this, however here I will need more sophisticated algorithm to understand where to show it and where not. Current implementation can expand/collapse literally any string, so kind of implicitly it supports even the cases when you use classnames or similar libraries.
