Documenting Campaign Settings

Since there is no undo, and no activity log of changes made to a smart campaign, I'm wondering if anyone has any suggestions for efficient ways to document all campaign settings; smart lists, flow steps, schedule.

For simple campaigns, screenshots are okay. But as smart lists get longer, and individual filters may have multiple items that don't all show up in default view, it's hard to capture everything in a screenshot.

Any input would be greatly appreciated.
