Firstly thank you, there is so much in this update that I can see being useful to me or others I know that use vMix.

I don't use list inputs a lot, but have recently done some work for a company that does, so I've looked at that first.

The Total Position indicator is a great improvement.

I think the remaining time shown below the program output has also changed to match if auto next is on. That is good to (if it's new). One confusion is there is no indication in that area if Loop is on - seeing it go red and start counting down can be a bit alarming when it will restart the list.

Could it not go red, and/or show something like (L) at the end, when looping is enabled?

I found one bug with the new Total values.
If you deselect a playlist item while it is playing that item will continue to play until it completes. The remaining time under program continues to account for it's remaining time, but, when Auto next is enabled, the new REM and DUR don't, but the POS does.
So you can end up with POS : 04:23 REM : 00:00 DUR : 2:33 and an inaccurate progress bar.

One other thing I noticed, which may be old, is if you deselect a playing item it will continue to play, but if you then deselect all items, play out will stop, go to a black screen, and not trigger any oncompletion triggers.
