Similar to what Metricool offers, would love the option revisit a post that was a huge success and reuse it. Sure, I can pull top performing posts from analytics and find the date in my calendar I originally published it, duplicate it and share on a new date. But would love an immediate "repost" option that shows up in the "Top Posts" section of analytics reports. This would save a few steps!
If it were me, I would then use AI to help me reshape the content slightly (different hook, different first slide if it's a carousel, etc)
