I like the way that when you update a preset, it updates that preset in all set lists (since it is a pointer)... Would like to see that as an option for the blocks as well.
If you are making edits through the HxEdit Stadium software, after you hit save, reselect the preset in the setlist (which is still on the left) and it pulls in the setlist on the device. So I hit save, then double click the preset on the left (in the setlist) and the floor device has the current set list available.
