I agree about keeping the bells and whistles limited, it's easy to bring a .txt file into something like LibreOffice when the main work is done so you can export it into a .pdf file. I would only ask for a way of seeing how many pages I have and/or a page numbering system. After all as a reader I don't find page numbers to be distracting, and I don't think they would distract me as I progress with my first large project or with any new small projects that I may start.
Such smaller projects would be started by me while following advice given to a group of us in a reader/writer's area of AOL back when dialup internet access was still a real way to go. The advice came from Ben Bova when he was a "guest speaker" there. He said that if you are going to be serious about writing you had to spend at least 4 hours a day writing, even if all that you write on any given day ends up in the trash. Using a computer I had managed to turn some bits of that stuff into short stories before being forced to set aside writing for a while. Anyway I'm finally back at it and I hope to actually create something that will be published. But then this info may be considered a bit off topic, so I likely should shut up and post this.
