I like that it can be used as an indexer in addition to searching, which makes it very useful for when we have multiple people working with different areas of expertise. It's also great for use by students who are doing research projects or reading books at their own pace. In some instances, it could take longer than necessary to load up a page - especially when there are many documents open at once. This is not always my fault though because sometimes pages don't completely load (and this happens more often if they're old). We've been using noggle since 2012 and haven't had any issues. The best part about using noggle is how easy it has become to find what we want quickly without having to go through so much manual effort.
