Nothing that specific. I tend to collect all my though snippets, conversation fragments, imagery I'd like to put in, and bits that I wrote but scrapped that might have something worth salvaging, into a big word file, to be sifted through when needed. When I start blocking out the next week or so covered in a new chapter, I just use a spreadsheet, creating some agenda-like blocks for each day, putting in the key events that will happen that chapter, and then filling out the time in between so the story flows from one event to the next and to weave in little side stories and things that strike my fancy. Its a format that works quite well with the day by day format usually encountered in slice-of-life VNs and sandboxes.
