I use Trello. I’ve got 6 lists on my blog board (Ideas, To Write, Writing, Complete & Unscheduled, Complete & Scheduled, Published). Ideas go on a card. I review the cards periodically and move them into the To Write list. Anything I’ve started writing moves on more list over. Then, when finished, they go to the first completed list. Once scheduled they’re moved over one more spot. Finally, when published, they make the final move.
