Riot please make it so that you can star friends

When playing on 5 man teams sometimes you befriend someone, play together briefely then hardly ever see them again. To separate those kinds of firendships from people you stick with for longer periods of time, irl firends etc can riot make it so that eitehr you can favorite friends so that they appear higher on the list or sort people on your friendlist by how often you've played / talked to them rather than alphabetical. i find it sad when my friend who im close with starting with letter S is so far down the list that i ddont realise that they are online. it is very frustrating.
