Hi,

Is it possible to have Rightwards Arrow Over Leftwards Arrow icon?

Give us an example of what this icon might look like.

There is already an icon like this, with the right arrow over the left one (but this is rather accidental): swap-horizontal. We should add an alias to make the icon easier to discover.

Swap horizontal is not a like for like. If you look closer the arrow bars are shorter. @Simran-B
