Hide personnal tabs in the player ?

You can use JavaScript (technically JQuery) to accomplish this.

1. Find your custom tabs and give them a unique ID.
   You can do this "At timeline start" on your very 1st slide. All of your custom tabs have the same ID so changing this to a unique ID will give you more control. The following example is for a course with 2 custom tabs. It will update the id's to tab1 and tab2. "tab1" will be the first tab found searching from left to right across the bar.
   $("#tab-customlink").attr("id", "tab1");
   $("#tab-customlink").attr("id", "tab2");
2. Now that they have a unique ID, you can execute more code whenever you want to hide them or show them.  For example, if I wanted to hide the 2nd tab but leave the 1st one visible, I would use the following:
   $("#tab2").hide();
   
   If I wanted to now show the hidden 2nd tab and hide the first one, I would do the following:
   $("#tab1").hide();
   $("#tab2").show();
