Just redirects you to your messages. Very simple. All I needed.

It does it job! I would have loved a way to disable reels and the feed separately, but it does not concern me specifically, as much as i understand there are people that would appreciate it.
The reels disable feature still lets you see
And the inbox only feature is just PERFECT. It redirects you directly there, so if you use Instagram for chatting only, it does the job.
One thing I would really want to see though: a way to disable recommended stuff in the feed. I want to see my friends' posts, but not the recommended stuff (the snooze doesn't really work at the end of the feed, plus renewing it)
I understand that the extension doesn't have a lot of users, and that trusting a small extension is risky, but in terms of functionality it is there.
