Requires COGS 5.3.0 or later
In COGS v5.3 you can now set the layer order of how you display media on a Media Master which is attached to a display. Go to the Connect tab. Open your Media Master settings and open the Screen tab.
By changing the layer order, it'll ensure that the chosen order is kept whenever displaying that relevant media on your display.
E.g. If your timer is set as your top layer, that will appear in front of your Background, any Videos, any Images and your Text Hints.
