Window icon open/closed

[HeinzRuetschi]

Hi Sergiu,

• it would be nice if you could also implement a window icon open/closed state and drop the current target value to an open window temp value as a parameter, till the window is closed again.
• A other feature which could be added is away or holiday in order to apply a different calendar.
• Unfortunately I did not find a way to send a different calendar which your node would accept.
• May be you could show an example in your documentation.
