I hate the new friends UI because the sorting is stupid as forget and you can't change it (it does A-Z depending on how many people are playing each individual game, then A-Z online, then A-Z away and such, wtf) and the chat menu tries way too hard to be modern and ends up looking ugly and disorientating

-nochatui -nofriendsui in the end of "Target" and in "Comment" of the steam shortcut properties (not the main .exe)
This is what I did to fix it
