We talked about this years ago. It is important to me now more than ever because snap is unreliable. I often have to check that the alignment I expect has indeed happened and a loupe would be great for that. What I envisage
And what would be really excellent would be the ability to select and move/manipulate an object within the loupe, but this is not an essential requirement. That would require the loupe to have handles to move and close the loupe such as shown in the attaced. (Note the mockup has been created using the magnify lens and as such the guidelines are ignored by the lens so the display looks odd)
