People who are new to the crypto world may have problems understanding how actually they are paying for a transaction and how much fiat money they are moving.
I use 8 different cryptocurrency with very different values between them (just think to the difference between ETH and MATIC, but I am sure you can think to bigger differences)
I would like to propose a small change to the UI:
add for every transaction a corresponding fiat price both in “estimated gas fee” and in “total amount”
This would ease life for everyone from newbie to advanced users.
I personally check every time the transation fees with a copy and paste and a fast check in an exchange. But sometimes being fast in a transaction is vital so I don’t do it, having it inside the UI would be a nice catch for Metamask. This could be also disabled by default and activable with a flag in setting
