Chord playback

I really like to play jazz, so I write a lot of lead sheets and scores with guitar parts that include slash notation and chord symbols. This means I use the chord symbols a lot, and this includes the chord playback. For some reason, the chord symbols don't like swing all too much. I found a work around, which is placing a triplet and the adding the chord symbol to the third beat of the triplet. It's one of those things I've kinda gotten used to, but it would be nice if the swing would apply to the chord.

I also find that sometimes the duration option doesn't always take, which makes it hard to make sure that the guitar part matches the rest of the score. Take the example I've included. If I set it to "until next chord" then it'll sustain through the rest, but if I set it to "attached duration" sometimes it'll cut off early.
