Improve Friend List

Somehow group the friend list alphabetically in sections and maybe an option to sort friends by servers or friends you share? A lot of space is wasted horizontally in the friends section. Could possibly have a more compact friends list so that I don't need to scroll heavily just to get to the letter 'R' for example. 

Another feature could be to have a timer of 'last interacted' with specific user (via voice call or messages) to help someone 'clean up' their friends list. Possibly show me friends that I have somehow added, but never messaged directly. example: I just deleted someone in my friends list that I did not have mutual servers or mutual friends with, and I cannot remember how I interacted with that person since there was no dm between them and I.
