I know it's been mentioned before many times, but I have to put in one more plug for being able to sort and/or filter the list by any of the xml fields. Mainly things like year, manufacturer, type, or rating. As more and more great contributors put out awesome work, the list becomes rather big to navigate even skipping by letter. I am aware some of those are included as built-in lists and that you can create custom lists, but that is not as easy to manage and still retains alphabetical sorting.
Still an absolutely amazing piece of software. So regardless, Tom you rock my world and I am so grateful for talented people like yourself.
