Adding the possibility to update a fork from Github UI

Hi,

I'm not sure if this is the best place to ask this question.

This is a question about requiring a new feature for Github, if it doesn't exist already.

Would it be possible to add a button to update a fork to the current state of the original repository from the "home" page of a Github's fork?

This could eventually cause problems in terms of conflicts, am I correct? Bu this could be solved directly by who's updating, i.e. the "owner" of the fork.

Currently, for me, the solution using the Github's UI would be to refork the original repo.

Thanks.
