Suggestion for the champion mastery system

Hey everyone, hopefully le members of supreme rito read this. I was thinking of a good idea to add into the mastery system where it can show all of the champions mastered/currently mastering instead of the top 3 and the currently mastering. I'd like a third page where it shows all of the champs mastered, that would be cool. Perhaps another suggestion could be (if you havent noticed, clicking on a summoner's profile will show the champions tab, grayed out,) maybe that champions tab on summoners profiles can be used to see what champions summoners have mastered and/or champions they own. Thanks everyone for reading, and possibly taking consideration towards this. Cheers.
