Add links to child commits on commit detail page

It would be nice to have not only a link to the parent commit(s) but also to child commit(s) if existent.

Currently, if I want to walk my way through a branch (e.g. a pull request) in chronological order I always have to go back to the list of commits to select the next one.

Walking through the branch in reverse chronological order is straightforward throught the parent link, but having the opposite option too would be an enhancement.
