With the Mint feature, I found that after completing a Mint command, the web will automatically clear the token pair I selected earlier. I think the UX design here has a good that users won't mistakenly execute double commands.

However, if I look at it from a different perspective, I am a user who tends to test a small amount command first to see if the protocol or network is ok at that time? If the small amount test is successful I will do the rest, so if I clear this token pair as it is, it will cost the user a lot of time to choose the token pair again. I think it would be better to keep the pair token option after successful execution but clear amount to avoid the user doing it twice.
