This first image shows what this device normally looks like

This second one is using the new pop out

In the second one the steps in the sequencer have disappeared. The little dot light that shows what step you're on, doesn't move and it's also showing a different editor mode when you bring up the pop out. Any MPs that are hidden using "Visibility" or "Enabled" are stuck in whatever state they were before the pop out was opened.
Anyway, great addition!
Hope that helps
