1. Converting isn't really possible because it really behaves very differently. Although I guess I could get close... but I think it's too much effort for a feature that has been deprecated for over 2 years now. Anyway, if I fix option 3 here, it might be much simpler for you to do it yourself.
2. Voice volume, interesting one - maybe I should add that to the new one too (I never thought about it!). Actually, it might help to replicate the sound of certain other processors
3. An overview window with the most important settings sounds like a good idea! I will make that.
