Autocorrection feature on MacOS
There is a feature I really enjoy on my Mac is the autocorrection while writing my messages. In Mail.app, if I type really fast and I misspell some words, it will automatically correct the errors. So I can go truly fast and not care on going back to correct manually.
I think it is kind of easy to use this feature in the MacOS client your are releasing. Could you improve your software in that respect?
