I am currently in the middle of switching to Bunq and I would love to see the option to automatically save the spare change from each transaction. Just like I am now doing with Peaks.
I know I can make an automatic transaction to save small amount of money, but as a student the spare change concept really does the trick for me to make saving a whole lot easier.

And maybe this is already possible... Than I would love to hear, otherwise just a suggestion from a new user.
