Like most people I have track groups. For the most part I load the majority of my show from from one track group but starting today I am including a set (15 minutes ish) from a different track group. What would be cool is the ability to create a Set (in my case about 15 minutes) Give it a name like "International 1". Then have PlayIt automatically fill the 15 minute set or manually fill the set. Then have Set name "International 1" show up in the right panel. Then all you have to do is grab that set and drop it into the show, move it up or down or remove it all together. Set's could be set 13 - 17 minutes or 15 + or - 2 minutes. (whatever time you wish) Just seems something super useful to me.
