For some reason I didn't receive the recent e-mails from Tom and Kyotaro. I've just discovered them accidentally by reading the thread through the web interface. These comments were not addressed in v21.
Aleksander, as of now we're preparing a new version that addresses a thing mentioned by Tom&Kyotaro. We'll try to add what you've done in v21, but please check. We're going to send a patch very soon, most probably today in several hours.
