I'm sorry for all updates but I really don't release them just to fool the crackers. I don't have a chance against them anyways... If you're happy with 2.0 and everything works fine you don't have to upgrade every 2 days... There are some remaining bugs in 2.0.5 which I'm currently fixing and tomorrow there will be the hopefully last update (2.0.6) for the next few weeks. you're also right - the core features didn't change and I can't force you to buy v2, so if you're happy with 1.5.1 and don't want to support the development, it's ok. I hopefully can work on new features soon which are maybe interesting for you to test v2
Anyway, thank you for sharing your comments, I'm glad that most of you understand my decision...
