This is one of the greatest clients in terms of custom features and I mean it.
BUT I can't help but say:
Why those lines do not align to each other? I mean I know they mathematically do, but they visually do not. (sorry those lines are not perfect, I'm on a phone lol)
1. Make Online list smaller, end it with 10th position of highscores, you'll have room for "Last Update".
2. this scrollbar in online players looks out of place (whole online list should narrower by the width of scrollbar IMO).
3. I'm on a phone so I cannot tell, but are those aligned to middle of Submit button? If so, then fine, but if not shift it somewhere or make those chooseboxes bigger so they match Submit button
4. It's bit... shifted, don't you think?
But I'm just complaining, this is a very good job. Keep us updated =)
