Option to choose between dropshadow and outline on the clock.
Option to control the margins of the clock. Currently There's too much unused space when you enlarge the font size.
Option to display TV network related info. Like is ethernet and wifi connected and VPN status. (Maybe show flag icon so you know what country VPN is connected to)
Analog clock. If you use webview to display the clock, then it can be easily implemented with SVG.
