From the main window to the settings window and vice versa.

It would be great if there were an icon at the top of the main window that let you open the settings, and vice versa. Or you could integrate the settings into the main window and switch between them with just one click.

So, when you click on the icon, the settings appear on the front screen and the main window remains in the background. Clicking the same icon again hides the settings, but the main window is still there.

Keep up the good work. 👍
