The Lighthouse team have just released a small to the communications log that works alongside custom objects.

Previously you would be expecting to see the name of your object, however due to limited space and the use of multiple custom objects by some customers causing a cluttered interface - the name of the object has now been replaced with the relevant object icon.

You can still review the name of the object by hovering over the icon. Clicking on the icon will take you to the page of the custom object as before.
