To the comment reporting lacking of Traditional Chinese
Ronnie.Hu
Spark is really a nice mail app that works seamlessly across different platforms with no pains. Plus the update frequency and reponse rate of the team are superb. I saw someone complaining on the lack of Traditional Chinese support in the comment. It's quite reasonable to request on a new language support, but it's ridiculous to express your hatred on Simplidied Chinese here. For me it's more to the country and people rather than to a language. How on earth would someone hate a specific language at all? There is another comment requesting traditional Chinese support, which I believe is more like normal request than express hatred.
