The author frequently provides incomplete answers to questions from many users on the forum, or assumes you know which file needs to be edited and where it's located, or simply doesn't answer questions at all, or just says that a question has been answered before and to search for the answer. As an example, I've had a simple question open for about six weeks and it still has not been resolved.
If you can overlook the sketchy support, then SimpleCaddy is a good solution.
I just started using Real Preview (free version) and it does what it says, cleanly and without problems. My first reaction when using it to preview an article was, "Thank goodness!"
Overall a simple and effective module. Thanks to the developer!
