I frequently find projects with really many forks. I then usually go through all the forks, only to find that most forks are outdated or stale. To do this, I have to open each one in a new tab, which is quite impractical.

This is how it can look:

each of those forks apart from the first one are outdated. But there is so much space to the right!
I think it would be useful to show for example n commits ahead / m commits behind for each fork.
