Rather, I’d like to see some of the old features come back. Especially viewing activity through the following tab. It was such an amazing feature with marketing potential, and then they removed it, ostensibly for the sake of personal safety. Only now all these functions are present in professional marketing tools, for example, Snoopreport instagram activity tracker. With it, you can add any user with a public profile to follow and receive weekly reports on which posts and hashtags they like; about their new followings and unfollowings; as well as interests.
And in general, if we talk about new features, it would be great if they added the possibility of qualitative analytics on the similarity of the data that I described above, and not quantitative useless garbage. Only qualitative data allows you to get valuable insights about the behavior of your target audience and actually gain valuable marketing knowledge, but, probably, such analytics are simply not profitable for Instagram.
