Sorry to keep everyone in the dark :-S
I'm very busy with my job and friends... For this project, I'm currently debugging the autoplaylist generation... There is many types of conditions, and trying them all is not very pratical... I'm currenly releasing a BETA version, 0.90. You can get it here: http://rocket.dyndns.info/mp3manager/mmwbe_v090.rar
(300Ko). if you find an auto playlist that doesn't work well, please contact me and tell me the criteria you used. I will try to improve that.
Please read the Readme file included for more informations about Installation and contacts.
