I use the following API Scripts from the Roll20 library:

• TokenNameNumber
• GroupInitiative
• GroupCheck
• Flight, which uses splitArgs

and the following API scripts:

• TurnMarker1.js
• bloodied_and_dead.js (modified)
• ApplyDamage.js

APIs that I want to add to my games

• Critical Hits - needs customized
• Fumbler as well
• Formation
• Control Player drawings (Dry Erase API)
• Token Mod (Aaron)

Create or find ways:

• Center window on who has initative.
• Track Rage or other status

Images:

• Spell Effect Area

Check Out

• Door Knocker
• GM Notes
• Concentration

Eventually

• Monster only mentions first time bloodied
• Fork Bloodied and Dead
