[Petr Nejedly]

• API
• integrate in the Console
• enable on-the-fly changes to the config levels in the console

can use this protocol: https://sweetcode.io/using-html5-server-sent-events/

or like Jenkins does it:

Writing to a stream

WriterAppender logAppender = new WriterAppender(new PatternLayout(), new    MyStream (outArea));
Logger.getRootLogger().addAppender(logAppender);

I don't consider this to be an essential feature on the product: - debug log would take too much output - would not work well on mobile devices - maybe detail switch will be done as a part of another ticket
