I like how you can use it for many different types of files. It's easy to navigate with all the tabs, and it has some nice features that make it easy to search through documents. You can also add more tabs for other file formats, and it looks really good too. There are a few bugs here and there, but nothing major and they usually get fixed shortly after being reported. I've been using this for several months now, and it hasn't given me any problems (aside from the occasional glitch). The biggest benefit is that you can easily search through a variety of different file types.
