Why?

I wanted something more than what OneNote provided. I was overwhelmed by OneNote Gem, aghast at its bloated useless overloads of what was already otherwise available or features that I would never use in a million years - and, oh yeah, that price! I admit I was intrigued by the Onetastic Macro approach but thought it limited and obtuse, decipherable only by programmers. And both of these charge money for something that should be open source and neither provided exactly what I wanted. So I did what any self respecting software engineer would do... I built my own.
