Downloaded this a few hours ago, and ported all my notes about my novel over to it, and I have to say: this is a really great piece of software. The interface is intelligent, ergonomic and fast, and it does a lot of things automatically which I really like. It cuts down on the boring book keeping.
I was also able to move my plot outline into this, which was a godsend for me because previously it was in a word document, meaning I couldn't check things off. Now I have an interactive task list for it! And everything is all in one place!
One small suggestion: I would really like some place where it lists all the key commands (for instance, are there key commands for making headings? what about the key command for Replace, which I couldn't find?). Also, it would be nice if tags weren't necessarily represented inside the document from a viewing perspective. Maybe as a bar along the bottom, which is then copied into the markdown document transparently?
Thanks for making this!
