i came here to suggest this feature! the way i'd really like to use it is make pages where certain auv3 windows live so i can easily just jump to their page when i want to get into their UI.

Yes please!! I would love this. I resize all mine to fit in a certain spot on my template and for the most part it works fine but when I full screen them and forget to shrink them again before closing them they loose their size and I have to resize them. If this would function so I could so shrinking it would would always default to this designated space that would be awesome.

One other note on it, mine overlap buttons I don’t totally need to see because they’re midi mapped. So if this widget could overlap others it would be great.
