Yeah, I had the impression it was just a 'trendy' but not very practical add-on to Word. Whenever Microsoft tries to be a bit more 'mac' in their design it just flops.
I'm writing a Sci-Fi book for kids. I'm using one file as my Encyclopedia of backstory, and one file as the actual novel. As I write I mainly use the "Document Map" function to jump between Encylopedia 'entries' like Character summaries and place summaries and raw, unvarnished plot summaries.
Does anyone have any other ideas on how I might jump around in Word, or even other (free) software I might use, or is it more efficient just to stick with software I know?
