When a user fills in the swap form, eg. 100 $rune for 744.707 $ust. Then clicks the arrow to change the direction of the swap, it shows as it would swap 100 $ust for $rune.

Proposal:

When changing the direction of the swap, the size stays the same. So after a user clicks the arrow it would show as it would swap 744.707 $ust for ~100 $rune.
