Mobile Friends Clog up Friends list!

Hey everyone! I wanted to make this post to direct towards the development team with a suggestion. I really like that a mobile chat app was developed so that you can talk with your friends that are online playing League of Legends! However ever since the mobile app for the game was released over 70% of the people on my friends list appear online as "mobile." Personally I would rather only see people who are in the client and available to play and it just seems a bit clunky to me having all these people who are basically AFK on my client especially considering that I split up most of my friends into different groups. I just thought I would make a friendly suggestion for Riot to maybe add an option on the friends list that would allow users to "hide" friends who are you using the mobile app. That way if a user wants to see if someone is online to just chat you can do so without having these users clog up your friends list! Thanks for any feedback love you guys :3
