Increase the width of the control panel

Hi! Can you implement the function of increasing the width of the control panel by turning off the right block with additional services? It is desirable to implement a button so that it can be hidden and, if possible, displayed again if necessary.

Bravo!! YES PLEASE, allow us to use much more of the screen real estate. Even on my small MacBookPro, there’s tons of white-space that could be put to better use (a better domain selector, for one).
