This update adds the following sized monsters from the Monster Manual;

Tiny
Small
Large
Huge
Gargantuan

Now that I have gone through the Monster Manual, let me know in the comments which compendium or book you would like to see monsters from, ex.: Curse of Strahd, Volo's Guide to Monsters, etc.

I am also considering adding spell effects, let me know in the comments if you would like to see these added as well.
