Some users have reported problems starting the π-console. We think that this is related to the automatic loading of the predefined patterns. Please, if you run into the same problem, for which we do not yet have a solution, please give us an email and we will update you as soon as that issue is solved. Sorry for that. Nonetheless, we highly appreciate feedback of any kind!

2. -reflection-completeness
