Perhaps this is a bridge too far. In case it is of interest, however, Edit Flow would be more useful to me if it had this additional functionality:
I want to publish a monthly online/print magazine that has 7-10 sections. I need to see a view of stories across 5-6 (or more) issues with the ability to move stories between issues. I want to ensure each issue is complete relative to other issues, with the ability to move stories to balance out content included in each issue.
It also would be helpful to see stories grouped by section. In essence, each issue is a parent category, sections are child categories of each issue category, and the stories are grandchild categories of each issue category. The only wrinkle is that sections can aggregate stories from multiple issues.
Once stories are in place, then it would be great to right mouse-click to create a post for that story and then enter the story into the existing Edit Flow functionality.
It also would be helpful to export the data as a simple spreadsheet (CSV is fine). I've mocked up a dummy spreadsheet here that shows the monthly issue view for 12 issues:
It might be easiest to emulate a spreadsheet layout (e.g. sections in left column, issues as columns to right of sections), with possibly vertical side tabs for each issue/month that, when clicked, open the column for that issue/month. The user opens the issue columns they want to work with then drag/drop stories, add stories, and so on across columns.
From a coding perspective, in terms of how to identify sections to use, perhaps you would create a new "section" taxonomy within Edit Flow? Or use user-identified categories under a root Post category (e.g. all child categories under Sections where the user identifies Sections as the source of the categories to use for sections)? The latter approach would get you the cross-issue view of all stories for a given section.
Basically, Edit Flow works great for daily blogging/publishing. If people are inclined, it would be great if Edit Flow also worked for managing editorial for monthly single issue publishing.
Hopefully this is clear. And, more important, hopefully it would be useful to the community to add this functionality. YMMV of course.
