Not sure if there's already a thread for this, or if it's already a feature and I just missed it, but I think it would be useful to have a search criteria for monster type (i.e. Giant, abberation, humanoid, fiend, construct, beast, etc.). I feel this would be particularly useful for certain abilities where you must select a specific type of creature. 

Again, it may already be a search tag that I overlooked, but I think it'll be helpful!

There is lready. Click on the different images on the top. They select the monsters per types.
