Vectorscope usability improvements

The current vectorscope UI as it exists now doesn't seem to complement its intended function as well as it should. There's probably many improvements that could be done here but here are two that I've identified:

1. It needs to be able to be larger. Unlike the histogram where often the rough shape is all you need to see, and small details are still quite visible at smaller scales, the vectorscope displays a lot of very dense, very granular information that is nearly impossible to see if it's not a sufficient size. ACR has an option to pop out the histogram and vectorscope into a hovering overlay which can be resized significantly larger. LR should either copy this or at least add the option to pop out just the vectorscope into an overlay that can be made larger.
2. A great feature of the vectorscope is that you can cut out all the unnecessary bits and look at just the colors of a specific masked area. Unfortunately you can only see that while a mask is actively selected in the masking panel. So if you want to do global edits, or even edits to a larger masked area, while focusing on the effects on the color of a smaller masked area, the only way to do so is to constantly go back and forth. The vectorscope really needs a way to lock its view to a specific area. Maybe tie it into existing masks so you can just select one from a dropdown next to the vectorscope and it will only show information for that area.
