Dear @mikew !
As we are the developers of the corresponding plugin, I just would like to write some official reactions here also to make more clear the situation to everybody 
The last some weeks wer very busy as we had to solve every problems what we did not think earlier.
We almost totally rewrote our documentation (the user manual of the plugin), to make it more clear how anybody need to use it. I refined the installation process and dependency handling almost to indefinitely, and based on the experiments of our clients I also wrote lot more detailed informations about the usage. Not there is separated block for just debuggin, testing, etc. so I really hope I could make everythng lot more clearer than usually you can reach such informations about any softwares.
We are really sorry for the rough start, we discussed really a lot about the plugin, and now after your unlimited patience I hope we could iron out almost everything, and in the future we could focus on really new functions.
As currently we have available clients who successfully use the plugin, I think we could already solve all the problems.
If you have any further question, please do not hesitate and search for us, for me here or directly by email.
The current 2.4.0 version is lot more friendlier than any earlier if anybody interested in.
Thanks again for your patience, and for the lot of testings.
