Last Viewed and Last Imported features wanted

I recently returned from a music camp where I used iReal Pro extensively while playing with others. I want to use my Last Viewed list to keep track of the songs I played, and Last Imported to keep track of the songs I received from others using AirDrop. There are two features I could use. One, keeping more than 50 songs in the list and two, a way to take the list and save it permanently.

Not elegant, but you might save/reference the list by grabbing a screenshot(s).
