If the Studio Panel is docked, it lacks a button to close it quickly.
The only way to close it is a long way through the menu View, Studio and finding the corresponding panel.
The second option is to undock the panel - click on its Tab, and drag outside the panels, when the close button appears. The disadvantage of this procedure is that when the panel is displayed via the View menu, it is displayed again undocked, so it must return to its original position.
The use of keyboard shortcuts for switching on/off individual panels is already difficult to remember due to their range.
An easy and logical solution is the context menu - right-click on the panel Tab, which we want to close.
