Thanks Sorin for the quick reply.

For our team, we are not interested in trying that app at the moment (since we are not interested in auto merging). All we wanted now is for the parent/primary ticket's status to change from pending to open when we merge other tickets into that pending ticket. Or what CJ Johnson mentioned in the initial request also sounds reasonable to us. 

Hi,
Thank you for replying to us regarding this new feature/app. 
I can see it could be helpful for some use cases (the same customer with the same email sent in multiple requests on the same matter). 
However, one of our primary use cases is merging 'child' tickets (generated by an automated system with a generic email address) to the 'parent' ticket (with actual customer emails). As you can see, the child and parent tickets we want to merge are not from the same email address in our use case. Therefore, this new app is not helpful for us in this scenario.
Feel free to email me if you need more clarification on our feature request. Thanks, Juan  

+1 for this feature!
