Currently the Sheet Reference Manager panel is static. As a result I can not see the reference name in full.
Due to cell reference limitation (100,000 cells), I sometimes have to remove references, but cannot see the full name so cannot see which ones to remove.
Making the panel expandable, by dragging the bottom corner, would expand the reference names.
Another way would be to select the columns to display. I use the source in the reference name, so the source column for me is not needed.
Another added feature would be to sort the columns.
