One great thing about Github is that you have the issues section, in which you can see recommendations or requests for help related to a particular project. There you can find many comments, where developers may be complaining about a bug, offering a solution, or simply pointing out something they want to see included in the project. If you want to quickly navigate through these comments and jump right into the ones that have had considerable reactions, then you can try to install this Chrome extension.
In each project, there can be a lot of comments, so if you want to go to the comments that have received reactions, Github Notable Comments can be useful. It is simple, lightweight and can be installed in a few seconds at the Chrome web store.
Once you have it installed, you can go at issues of a project and look at there.
Let’s take a look at this issue on the Rails project. It contains 66 comments, but you are only interested in reading the comments that will be the most helpful. You can do that by simply using this nice little side-bar that is added and navigate immediately into the comment that has received the most reactions of that kind.
Yes, it is just as easy as that.
It is open-source, developed by the developer of another really helpful Github related Chrome extension called Githunt. You can find it here on Github.
