Widget issues on local server setup

@alcal ok

  1. Historical graph - need investigation; We will check;
  2. Please update to latest library (0.4.4). We made changes to it recently and code examples were updated; Should work fine;
  3. Hard to give you an answer. It could be your mistake as well. The best way to find out would be to enable server logs with log.level=trace. So you can see every command that comes to server and goes to app;
  4. Probably now is seems unnecessary, but at the start it was like a feature and right now a lot of logic based on that. So there is very small chance we will change this.
