Changing a tag display name

[antonmb]

I have been using the "Comment" tag field to indicate new music added, so for example for all new music I import this month I will set the "Comment" value as "May 2014." This allows me to then see more recently added music, similar to the "New Music" sort that Logitech Media Server has. I use the Comment field because it's readily available on most OS ripping apps like XLD and Phile Audio. I'm using Kinsky as my control app on an ipad and this system works well. The only problems are 1) music with no value in the field shows as ”Unknown" and I'd like to not show this and 2) I'd like to be able to change the Comment tag to display as "Added". Anyone have any thoughts? Or is there some easier way to do this I've missed?
