You can either use icons or turn on the "Cycle Actors" option. (Or even both at the same time!)
There are multiple ways you can handle icons. The simplest for a non-coder is to use this plugin (it's free!): https://heroicjay.itch.io/actor-icons NOTE: I never updated this plugin for MZ, but setting an icon through <icon:##> should still work even there.
"Cycle Actors" is an option in the plugin settings. It makes it so that only one actor's details appear at a time, and the displayed actor will cycle every second (by default; there's also an option to make it shorter or longer.)
