Improvement in Instagram's UI/UX

In present UI ,
If someone wants to follow any account showing in his Instafeed, he needs to follow these steps:

1. First he need to tap on the name.
2. Then he will be directed to the Profile page.
3. And then here, he can follow this account.

The problem in this UI is that, usually a very few people go to profile to follow someone.
If people love any post,
they just like and then
swap it up.

And in my suggested
improvement people can follow accounts even in their feed with just one
tap on the follow button.

if you like my idea, then please appreciate...
