I try to explain, but it’s tough 
you want to build 2 lines of chords using Suggest (Live or not)
At the last place of the 2nd line, you want a chord that matches with the 1st chord of the 1st line, so the loop flows perfectly… Doing that is currently troublesome
So having the Suggest option that shows you a series of chords to choose among, and that are musically correct to connect the two parts of the loop could be a gem
