I suppose everyone has their own idea of what needs improvement first, so I will add my one idea.

IYT has a feature that declares a winner (or tie as the case may be) in a tournament section once it is mathematically over. Once all sections have a winner, the tournament progresses to the next round.

Such a system would help speed up tournaments without having to wait for stragglers who can have no impact upon the overall results.

I believe that if BK implemented that, then there would be more satisfied players in current tournaments, and more people might start playing in tournaments, which would help BK retain players.

I have no idea how easy or hard it would be to program such a situation here, and I also know others surely have other ideas which perhaps ought to have higher priority when it comes to making improvements.
