Sometimes you have to take very quick action. I noticed when a transaction fails I need to go back to the gas tank page and look at my balance. It would be great if the gas tank widget be also displayed on the swap page directly. See the attached screenshot.
Upcoming extension: Within the transaction cart window, you'll have the ability to choose from a dropdown menu the account you wish to utilize for gas fee payments. Similar to the existing gas tank functionality, you'll be able to conduct cross-chain gas payments (depositing funds on one network and using them to cover gas fees on any supported network) and saving approximately 20% on gas.
