Paddy,
The bug I have found is not something new to this version, but I just confirmed its existence.
What happens is, if it's your first time running the extension, and you try to configure it through "Settings" instead of "Setup Guide," the extension freezes. I have tested this on two computers so far, and it occurred on both. If you restart the extension, it's good as new.
So this should not affect the scheduled release, but it appears to be an easy one to solve.
Thanks for your continued support and development,
Ahmed
