1) Line numbers for the “Playlist” box as an option. I had a situation when I was running two vMix laptops at the same time so just to make sure I was in the same location on both laptops a Playlist line number would have been very useful.

2) To be able to do a bulk select option where I can apply for example a “fade” to multiple items in the playlist at the same time.

3) To have a Playlist as an input option inside a Playlist.
As an example, I have a preshow playlist of multiple images (slideshow) and videos on a loop and then when the show starts to step out of that playlist to the main show playlist. If there may be another way of doing this, please let me know.
