For people that are the target audience of this, I'm curious - what do you like about putting the information into a gui and using a mouse instead of a keyboard?
I don't have to remember anything to use it, I just click self-explaining buttons and the thing works. The search function is also very nice, and navigating an outline view with the arrow keys, quickly collapsing subtrees as needed, is a very useful tool. Also, drag and drop.
In my experience, CLIs are great for efficiency, if I am doing a task so often that it becomes rote behavior and learning the tool is no longer helpful, or if I want to automate it. I find my real world need for either of these to be relatively slim, but I am not surprised that it is common for others.
