PyS60 on device debug ?

A simple matter makes me suffering as I'm new to PyS60 development.

What is the IDE for

• Executing program on-device with a single reasonable amount of clicks,
• Typical step-into, step-over, run-to, watch (used from PC) for the on-device running program ?

From stackoverflow

• Real on-device debugging is not (yet) possible, I'm afraid. You have to use popup notes, audio.say() or write to log files.

  Personally I forward sys.stdout and sys.edterr into a log file and use sys.settrace() and sys.setprofile(). Works reasonably well, no need to modify real app source code, just dump EVERYTHING into a log file and do search afterwards.
