hi martin,
i frequently use the multiview function. there are three issues you could maybe address at some point.

1 the new function to store a specific multi view setting is great. It would be nice to be able to name them.

2 in the layout it is difficult to exactly align the multiview. it would be handy if the alignment in y (vertical) uses the same baseline and preferably a selectable snap to grid (5 or 10 px) function

3 when aligning the multiview i noticed something strange: having aligned the multiview exactly on the lower side of the inputs in preview the multiview is shifted a little in the recording view. why this is so i can not explain. it is something in vmix itself.

now i have to align and then shift one of the inputs 1 or two px so in recording they match.

ps. i use a multview in overlay mode, so that a powerpoint is big and a video of the speaker is small. the pp ( desktop capture) is over the video which is 'cropped' on both sides: left with the overlay pp and right outside the view window.

the lowerside is exactly aligned. that's where the pixelshift occurs. See video below with example multiview use.
