That is an alternative, but it has to wait for next hand to be effective to all tables when I am multi-tabling. Sometimes I need it to be effective immediately. If there is a hotkey for snap hide/show HUDs will be much better.
Another situation is when the game ends, HUDs still exist and make it difficult to view table info when I am choosing a new table to join, and since the game is end, there's no next hand to let the HUD changing be effective.

Thanks, I found it, but I think it can be more conspicuous.
Maybe using the same refersh button will make the UI more consistent.

However, If it can be automatically refresh when a new hand is collected will do the best (or make it an option let user decide auto-refresh or not).
