Thanks Dan,

Good to see the code has made it to the plugin repo.
A reference on the wiki is fine of course. The more info the better.
 
Renaming the plugin to a less technical name is a good suggestion. I have created an issue for this.

Let's see if there is any interest with hopefully some feedback. Might take some time now the northern hemisphere is going dark and wet for a few months (at least over here :-))
