I am using the bookmarking feature on the Stack Exchange forums a lot to use later and it is saving me a lot of time when I am faced with the same problem again.
So i am wondering how it is possible to save a comment on a GitHub issue for later, as on stackoverflow there is a bookmark button under the “downvote” button.
For now I am saving the URL in my browser. I am looking for a better method, if there is one.
What are your methods?

I am writing this post on stackoverflow because many people use GitHub on stackoverflow and I think they would benefit a lot from this feature. Feel free to suggest a better Stack Exchange forum if this post is inappropriate here.

I searched all over github to find such a feature and found only the subscribe button, which might be fine for closed issues, but I don’t want endless notifications about open issues. I would like a better method than saving the URL because it is limited to the browser I am using and is not targeted to the single comment I need.
