Please don't change the fact that you have to type the county names in full each time, I think it makes more thorough. Also it makes it easier to type out a lot of answers quickly without having to keep checking if it accepted an answer earlier than you expected.
Maybe make it clear whether it's the historic counties or the modern ones? I started with Ross-shire, decided it must be the modern ones, tried Western Isles in English and Gaelic and then gave up. Just a little note at the top would be a help.
These counties are from quite a while ago. More divisions now in populated areas, and I believe we have to refer to Western Isles 'Na h-Eileanan an Iar' !
