Not sure if it’s an easy feature to implement, or if it’s already there and I’m just not seeing it, but it would be great to be able to search PM’s. Running large sales threads is pretty tricky and this feature would help to correlate orders to usernames and such.
Good idea, Hoop!
I would like to be able to search Private Messages as well. 
Yep, I’d like that as well. I wonder if father xmas (sb) can get his elves onto it?
