IMHO, being able to edit tag boxes in the preview would be perfect. 
Since it would make sense anyway to display them there, when browsing 
photos.

However, depending on how the actual detection/recognition is 
implemented, and since it looks like it will be a time consuming 
process, maybe an extra non-modal window would be nice, which just shows 
all images where the system wants to ask the user what to do with the 
persons. As an alternative, one could add a new tab on the left side, 
call it "Ongoing face recognition", and the user can check the status 
now and then while he works on other photos, and interact with the 
tagging process.
