Skill combo tree

I think it would be great to add a tab in the skill window where you can see the combos and skill chains listed.

This is an image from Aion with basically what I thought would be good to implement here:


This makes it easy for players to fully understand what skill triggers which combo and how to chain them effectively. You could provide only the information that is already available and leave the more obscured / advanced combo for the player to figure out.
