Currently the “+” icon that signifies “adding”.does just one thing it opens a new tab. And to open the other tab types the mouse pointer has to travel to the 3 dashed icon on the opposite side of the monitor.
I would suggest that it would be very beneficial to have the option to right click the “+” icon to open…the four types of tabs/windows that appear in the settings panel or more accurately the options list icon appearing as three dashes.
However I would also state the drawback that non-technical users and grandma might be put off by too many options perhaps.
But moving forward I strongly believe that this is a very good feature.
