content: Disliked it at first because it seemed too simplistic and limited. I wanted something with the power of TreePad which sadly isnt supported anymore. When at work OneNote 2013 was the only option I forced myself to use it. in doing so I found it way more powerful than I expected  such as the ability to collapse indented text doubleclick on the heading. Being a SW engineer myself Im very impressed by its features crosscompatibility and ease of use.
