Credit Card

Hello,

I am a new user, but I miss a functionality I saw in other similar apps, Credit Cards.
I use a lot my credit card, and then transfer the money from one of my debit cards to it, but I can not add the Credit card in Moneycoach.
The only workaround I could think at was to just add a new account with negative amount (sum that I owe to my credit card), but it will be more useful if we can mark that account as a credit card, with a limit on it.
Otherwise, I really like the design of the app.
