Suggestion - Friends List

I don't ever use this forum but since I don't want to bother the ticket guys I'll do this here.

So, I've been playing since 2009 and for almost 6 years now. In that time you accumulate alot of friends. And now I pretty much have to fight with the "max. 100 friends" limit every day. The most annoying thing about this limit: In order to put someone else in the list I have to remove one of my friends. I usually do that right in the lobby, but as soon as there are more than ~20 people online in there I can't even scroll past the online people. So I have to go into the friends menu and pick somebody (at random most of the time cause I don't like having people wait for me).
I'd love to have a button that removes inactive friends (e.g. >6 month).

Or if the servers can handle it increase the limit alltogether, so I don't get people being like "yo, I'm [insert name here], you remember me? You removed me from your friends list :(" sometimes when I do random 1v1s.
Any work on that would just be fantastic!
