The current UI is not the best, and can be improved a lot.
1. The number counter - 1/2 - at the top of the widget can be moved in the space between the left & right arrows at the bottom. That is not only the proper position for the number counter, but would also free up some space.
2. For the weather widget, the arrows can be placed a little lower than they currently are.
Once these two tweaks are implemented, the size of the widget can be increased. Eventhough its cool, its a bit cramped up right now.
