Describe the feature

A lot of banks (at least in my country) charge you a fee for transferring money between your accounts and because Maybe transfers the whole amount it does not show the correct total amount in the end (usually not a big amount, like sub 0.5€ but in the long run it adds up :)). Also maybe add an option to choose who the bearer of the fee is (the receiver or the sender).

Why is this feature important?

The current work around is to create another transaction alongside the transfer transaction for the transfer fee. This would save time for such occasions.
