Glad the leaderboard is still on beta, here's a list of my problems with the leaderboard:
1) You can't move just like the previous leaderboard ( we used to able to move and Press TAB in the same time)
2) Ability to sort my leaderboard by Jobs , name , money , or even ping.
3) Takes too many spaces on my screen ( on the old one i could tell what's going on to my right & left)
Before:
After:
4) The "Currently active player" that's in the buttom left corner is too small and coloured white so it's hard to read
5) Just like Dexx said maybe make the TAB Menu Useable for copying steam id , opening player steam profile , or even see their whitelist.
