In the countries list, where all the countries are listed, and the ones in your collection display the number you have in brackets right after the name, would it be a very complicated fix to put no brackets after countries we don't have? Just leave them blank.
So instead of:
CountryA (0)
CountryB (0)
CountryC (7)
it would be:
CountryA
CountryB
CountryC (7)
which would copy much better into this:
Country Country2 Country3 Country4 (7)...
When trading missing countries lists with others, the extra 'space-bracket-zero-bracket' after each line is a pain when editing.
Anyone else bothered by this? Anyone... Bueller... Bueller...
