What is White theme?
The White theme is the name for one of LiveAgent’s agent panel themes. Its ancestor is the original grey theme, which was used to develop a new, white alternative. The design of the white theme is cleaner, however some customers still prefer using the white theme. Currently, all new LiveAgent accounts are set with the White theme defaultly, however, you can change the default theme in Configurations.
Also, Agents can set a theme that they prefer.
