Hello,
We should have the possibility of disabling table mesages like who created what or who left what. This gets very annoying when you create a game and are waiting randomly for a player.

we do , go to options , then reading and appearance and choose customize global messages , there set speech reading to never and you can enjoy.

A question: Is there possible to hide the who joins and Creates new tables etc? I am asking that because the web client.

No, that's not possible to change into the web client at the moment. The previous parameters are available just on the windows Client, so if you don't want to listen to those messages simply go to another window or switch to another opened app in case of a movile device. Best regards.
