I'm using this one at the moment, seems to work fine with PoR. Don't let the preview decieve you, it contains the files for all three windows, so you can just use the group window if you want to. That about what you were looking for?
Thanks for the suggestion. I have tried it earlier today, but the UI couldn't load with that group window added, which was strange as the complaints I got was for undeclared entities which aren't actually in the file. I have to look further at that.
