I just signed up now, and I was expecting to have to go through a number of loops to get it to grab the data from my multiple bank accounts, but it was a breeze. Just another step in the sign-on procedure - truly great work on minimizing the number of people that default from linking their bank accounts.
And the UI is goal-oriented with a deep understanding of common tasks people want. I saw my transactions and renamed one of them..... and was about to groan how stupid this going to be, renaming everything else to match, when I saw the "rename all other instances of xxx always" option. I was floored.
Great work, Mint!
