It's a tool to help transcribe and share sequences of skills.
Select your class, and click or drag skills to the skill area. When you want to share the sequence, click share and send them the url!
It indicates the skills that don't share the global cooldown.
I've added Dawntrail skills. It's currently missing information on which new skills are oGCDs.
If anyone is able to get that information to me, I'll update the skills
