In the previous version, you could toggle highlights on DOM elements as they (re)rendered, which was quite useful for debugging. This feature allowed you to see if a certain reactivity was updating more than one element, such as a list of items that should only update a single item when something changes, rather than all the items. I can't seem to find this toggle in the new devtools. Is it still available, or is it something that's planned for future updates? _Originally posted by @puyt in https://github.com/vuejs/devtools/discussions/111#discussioncomment-11253060_
