Increasing Access

The Current Icon arrows can not depicts anything to the end user to understand whether this is used to view all the source files or not.

On the first time, I also not able to understand that this button helps in viewing src files but when I looked it in mobile then I thought this button did this thing. So, it's better to update that icons with the same as used in mobile view.

The button icon should be the same as on mobile devices on the desktop.
