Developed at Alan Yip, Overview sits in your notification center and currently has the ability to manage mail, reminders and events -- with more on the way. The developer is even thinking about the idea of including plug in support so other developers can create their own additions.
The quick action function lets you mark the item as read, flagged, complete, or delete. The list function lets you view your mails, reminders, and events. Finally, the shortcut function lets you create a new item.
The tweak will be a paid addition to the Cydia store. Owners of Tap to Widget will receive a discount. No word on a release date yet.
