First of, hello you all

After installing the RTM Trail Version on my Netbook (Lenovo Ideapad s10) and liking it a lot, I also installed it on my main System.

Now one thing that I would like to get done is there a way, as in the online version of outlook, to change the setting in the Mailapp so it shows only a list of Mails instead of open the mail directly? Could not find any settings for the MailApp.
