I was posting this as an issue and found that you can use ‘Edit’
or CMD + Enter
To resize a Frame or Graphic with numbers in the inspector, and it won’t resize it’s content.
You can use CMD + mouse to do it, but it’s the only way to do it numerically.
I wished there was a bit more feedback in the inspector that the mode is on. Maybe blue hihglight in the width/height field.
Is there more feature to the Edit mode? Does it affect anything else than the ‘cropping’ of the element?
