Thank you everyone.
Yes I think REAPER 5 scripting capabilities is going to be one of the major features and strengths.
I'm also excited with this script. It has convinced me to accept paypal donations, since some of you wrote me privately for a donation address. But I will announce it properly when it is ready. I am working on a web page where you will be able to find all my scripts and all updates so nobody will miss anything like in the forum
