Code review comment for lp:~rpadovani/ubuntu-calculator-app/1214395

I have 2 questions, the first being why do you explicitly state the font family? Isnt the Ubuntu font the default? (This is more a question since I do know it either)

font.family: "Ubuntu"

Also why do you Text {} instead of Label {} to display the date or anything? I think since Label is part of the SDK, it will automatically follow the SDK design styles. Correct me if I am wrong.
