It would be very useful if the number of available tracks and number of expected tracks could be calculated into a Percent Complete score that could be sorted. The user could then sort by percent-complete to quickly find all the Gold Records, but could also disaggregate the nearly-complete from the singles.
What exactly is this referencing? Is this a proposed Picard feature?
Hi @milesmac

You might want to make an account on the ticket tracker to vote on and/or watch the ticket for any development—or if any developers ask questions about it.
Also, if you have more feature requests, just post them directly in the ticket tracker. 
We already have remove perfect albums plugin, I am not sure how useful this will be? Thoughts?
After the perfect albums are removed, a user could sort by percent completed. They could then focus on completing those albums that are only missing a track or two. As it is, there is no easy way that I can see to isolate or segregate almost-complete albums.
