I believe this is something our team is already aware of, however, as much as we want to work on this, it might be way too much for our team to work on and the fact that such daily ideas will still be far from what you might want to make a video on, it'd be better If we just do our personal research and use search engines rather than making an entire feature.
This has already been suggested in the past however, we're not planning to add it for a while.
For example, our channel is about holidays and retirement. So TubeBuddy will give us all days suggestions for new videos that could potentially become viral because there aren't many about that subject or because the competition are low. Those daily ideas would be according youtube or Google searches for that niche.
