League Interface Suggestion

I'll try and make this quick. When I open up league I often look at my friends list (specifically at the ones I play with a lot) and check how far they are into their game. If they are far enough in I might wait for them to finish so I can join them, but this brings me to my problem (and assuming I'm not the odd one out many other people's problem too). You never know if their game is gonna be a 25 min game or a 50 min game and all you can do is hope. I feel like I've thought of a somewhat reasonable solution to this though so that's why I came to the forums. As we all know league loves stats. All kinds of stats. I feel like using some formulas based on champions playing, current K/D/A of the players, and time into the game, league could make a pretty accurate guess as how much longer a game will last. The next step after making a good game duration guesser would be to make its guess visible to us. Obviously we don't want that number standing out as important so I suggest making it where if you hover your mouse over the current time into the game it will bring up a small little box above that tells you the time and stuff. ... If this is added I'll be happy because I can stalk my friends better ( ͡° ͜ʖ ͡°)
