Help Desk Addon Alteration

I'm hoping someone who is using the Help Desk addon (from Sno) could help me with a modification.

I'm trying to show the “last replier” as a column in the admin panel on the page where you can view all tickets.

Currently, the “last replier” shows up nicely on the customer's side, when viewing their tickets on my website, but does not in the admin.

As tickets continue to accrue this would be a nice feature to have. Right now you have to expand all the tickets in order to see who the last replier was.

Any help would be much appreciated! Thanks!
