Pins that belong to different power banks are displayed with a different background color, which improves visual distinction between pins from different banks. The banks are displayed in three colors in such a way that banks 1, 4, 7, etc. are displayed in one color, banks 2, 5, 8, etc. are displayed in another color, and banks 3, 6, 9, etc. in yet another color. To disable bank display, uncheck the View > Device > Show Banks menu option.
