I know that in the desktop version of the old Scratch, there is a menu button that allows you to see (very slowly) what code is currently running by highlighting the blocks (The opposite of Turbo). Is there something like this currently in Scratch? (If so, how do I use it?)

If not, I would really like this feature to be re-added. It has helped me numerous times while debugging, and would be a great asset. I find it frustrating that I am not able to see what is going on in my project.

You can only do that when you click “See Inside”. By the way, the whole chunk of block lights up, not the specific block that is running right now.

This belons in suggestions.
