This is my first post and I’m only using jaikoz for a couple of days. So if I say something stupid: Sorry 
A great feature of jaikoz is that it shows, nearly, all tag fields and even highlights leading and trailing spaces.
I would like to see an option to automatically remove those spaces.
And while at it remove any empty fields.
I also seem to have quite some tracks with duplicate genres. Maybe it would be possible to dedupe multi value fields?
