Toolbar buttons

Thanks for great program

When I use the program I have one little thing that irritates me.

The toolbar have 4 buttons - parent directory (yellow) + root directory (yellow) + home directory (white) + refresh (green)

I always makes the mistake that I push the wrong button when I want root directory or parent directory because they are both yellow !

Is is possible to switch the color of one of the buttons or even better switch the order.

Thanks in advance

Ok, but it's a convention that folders are rendered yellow and all other WinSCP icons with a folder indeed are.
