View all thumbnails in speaker view

Is there any way to see more thumbnails for non-speaking participants when in speaker view? When someone is screen sharing, I can view side-by-side with the shared screen (usually a slide) on the left and many participant thumbnails on the right. However, when I'm in speaker view, it only shows six thumbnails at top, and everyone else is off screen.

I like having the speaker be in the center of the screen, larger, and highlighted. However, I hate that this means I can only see six other people.
