How do I get rid of this panel on Rhino

Hi, super dumb question but has been bothering me for a while and cannot fix it…
Recently my rhino decided I want this render panel to block out my entire viewport. How can I reset it back to the main panel?

Hi Ela - if you do not want them at all, you can drag them out from the left end to float them, then close them, or put them all in a single group by first floating then dragging one into the other to nest.

thank you Pascal!
do you know how I can get the original (the main) panel back?

Hi Ela - run the Toolbar command - there you can see what toolbars are available in the Vray toolbars,.
