I raised a support query over 2 years ago. Okay, nothing is broke but it asked some questions about use and some suggested improvements. Even if they didn't want to take make the changes, some acknowledgement would have been nice. But there's been nothing. So, nothing suggests to me that if I use this plugin and it breaks, they will offer any support.
However, right now, it does work and works well, hence the star rating. However, right now, although I'm experimenting with it I'm nervous to use this in a live setup, for the above reasons. I'm hoping the developers will respond to this and put my mind at ease.
