First, I love the new grid preview mode, it allows our team a lot more flexibility in seeing what's upcoming and jumping around if needed. However, we've noticed that when advancing through it during a normal service, once you reach the last item in the grid (e.g., current slide is the bottom-right grid item) you have no idea what's coming up next. This has caused us some 'oopsies' moments where someone has inadvertently advanced to the next song thinking there was another verse left, or clicked on the wrong thing when trying to scroll down to see. I think a very straightforward solution to this is to make the current slide selection always be one grid line before the last grid line. That way you always have a chance to see what's coming up next.
The second, a common use case for us is to have a few songs after each other, and sometimes the worship leader will talk a bit before the next. We usually blank out the slides using the quick screens in these cases. However, if you use the arrows for next when we're ready to move on, you end up showing the lyrics to the last song. The only way to seamlessly advance from blank screen shortcut is to click on the next song item. Given that there's a quick screen for 'last slide' already, wouldn't it make more sense for "right arrow" action while on blank screen to go to the next slide in the service? That would save a click, and make keyboard-driven service running a lot easier.
Thanks!
