Custom icon of maximize tabset button

[N8th8n8el]

Is there a way to change the maximize tabset button icon? Same as closeIcon prop of Layout?

If you want to modify the icon at once, I don't think this method is suitable for now.

You can participate in the discussion #150.

For now if you want change the icon dynamically. You can change the classname of the button with cm function.
