Thank you very much for the offer Peter.
As a general point, beta testers for plug-ins are always extremely welcome.
With regard to these particular plug-ins there will be a need for beta testing before release of any new versions but I don’t think that we are quite at that stage yet.
If you’d like to do some beta testing now, there are two new plug-ins that are currently waiting for testing before being uploaded to the wiki download pages:
