Looks good, only one clarification, is the VEP related feature can be generalized and used in the feature viewer, i.e to add another functionality on AA selection?. Please merge.

Is this to support VEP related feature?

Yes, this is the event we're calling when the user clicks on the Get Predictions button, it retrieves the final variant values added through the popups.
