Currently Actor Studio only supports Player Characters. Something that may benefit DMs is the ability to use it to create NPC's.
Instead of selecting Race, Background and Class... for NPCs the DM would be able to select a creature type (e.g. Undead, Beast, etc.) and then filter selected compendiums for that type of creature.
The GM would then choose one creature as a template, or starting point, from which to create a new NPC / Monster actor.
In addition to the template chosen, the GM could then see list of Features, filtered by creature type, gathered from all the actors in the assigned compendiums.
CR and HP formula will also be adjustable
It might be fun to have an automatic CR calculator built in
