It's like short-hand quest-specific VCE. This is convenient for new users, or for those who simply don't understand VCE.
However, VCE is actually more advanced than this, and can be used to do the same things and more. The main power with VCE resides in being able to state and call functions, along with being able to string the events.
This mod is great for basic eventers, but most advanced eventers will find VCE to be more useful. I am sure people will still use this too though. Nice work.
