Option to only show favourites in champion select

Whilst I love that we now have the option to "sort by favourites" I still find my screen full of champions I don't even want to consider during champ select. It would be great if there was an option to "only show favourites" so that you can quickly scan across your champ pool deciding which one is optimal.

At the moment I find the sheer volume of champions presented visually overwhelming even when sorted by role and favourites, whilst trying to balance team composition, counter picks etc in my head at the same time.

I realise this isn't exactly a major issue, but thought it would be interesting to see if anyone else would like it implemented as well.
