feature request: filter to sort games by opening

In my opinion it would be great to have a filter which allows u to sort your games by opening. I think it could be beneficial for many players to be able to see how they're handling their openings vs. opponents of different strenghts.
What do you guys think?

..or
is there already a way to filter games by opening on lichess?-I couldn't find anything..

Would be nice for sure.
