Dear Mike,
thank you for implementing this feature in the latest update and i am sorry for the windows trouble in the last days 
The smart button to song position works, but with a little bug for me:
if there is one audio file already connectet to the song then the smart button start does not work. I have to load a second audio file (or the same) and switch between those two during the smart button configuration. Then it woks perfectly. If you have time, mabe you could have a look.
Btw: Your doing a great job, the possibility to get in touch witch the developer and he is open minded for the wishes of the users is really awsome.
As a point for the Wishlist it would be great to have an even smaller (maybe half the Size) of the small size smart button. Because i place the buttons between the staffes and there is even the small one a little too big. And maybe the possibility to hide the buttons in case you do not need them without deleting them.
Thanks again.
Silvio
