Hello, I would like to share my ideas about some widgets improvements.
Mail:Basically I believe that there should be a manual refresh.By default mails are received based on schedule (set by user).Thing is, automated mail checker consists of a great battery consumer.
Social Widget: I think that button arrangement should be altered in order for the widget to be more user-friendly.As an example, the refresh button placement, at the bottom which the user needs to scroll for reaching it, is a bit irritating/frustrating. You can easily add a refresh button like BBC/Reuters RSS feeds widgets.
Weather(judging by leaked version) and clock widgets should be joined in one unique widget(in order to occupy less space) with date in white bold font linked to calendar. Also flip clock would be an interesting change.
Also delete button should be a bit bigger cause sometimes deleting widgets becomes an irritating event(especially if you don't have thin fingers)
Here is some photoshop work I did (just to get an idea)
