I like that it's easy to use, but not too simple. It does what it needs to do, and has a lot of options to customize your own workflow. The fact that it's keyboard driven is great for me as I'm always using my laptop at work. I dislike that when you're in the "edit" mode, there isn't a way to copy/paste text from another document into the edit window. This makes it very difficult to edit large documents if they are stored elsewhere. This is one of those programs where you have to get in the habit of using it every day. You'll find yourself more efficient with its capabilities. We've been able to improve our time management and organization of projects by using Checkvist.
