I think this is correct. The custom logging to file in ~/.../log/ can be enabled here.
However this logger was practically unused.

I have reused it, and fork more message into it  so it become much more usefull.

For system log, I would choose different approach. I would let it enabled by default, and allow to 
disable it in itw-settings - I will add this as separate patch once refactroing is inside.

No, you are doing it right. But you are an developer. And good one. I As pavel mentioned - many 
users can not find even the terminal...

Well, I'm checking them quite soon ifI tryu to find any debug outputs...
