@sgiehl can this be merged?

Just looking at the code, the changes look good to me. But I have actually never used or worked with the plugin. So it would take me a lot time to get familiar with it in the first place, for being able to prove that it still does the same as before. Unfortunately I don't have the time for doing that at the moment. Not sure if @AltamashShaikh is familiar with the plugin and can take over here.
