Smart Focus is an assistant feature, for both the mobile and desktop app.
*Smart Focus is not available for Apple macOS.
When you are playing on multiple tables (more than one table) at the same time (multi-tabling), Smart Focus will automatically change the table whereby tables that require action will automatically be brought to the foreground.
Please be reminded that if you move the table by your action, Smart Focus won't change the table automatically, until you make an action on the moved table.
*You can disable Smart Focus via Settings.
