Oh I see.
Thanks for the explanation Deano, I always wondered why it hadn't been done yet and now I know.
It sucks though seeing as the first letter can change or words are switched around after translating countries. This ends up making the list unorganized and a little harder to use in other languages.
Maybe it could work if there were a Countries Menu in the Builder so you can drag/drop the countries and reorder them the same way you would other items in the Builder. Only thing is you would have to change it for every language so I guess it would take up to much space and make things more complicated.
In the end speed is more important so I guess it's something that will just have to wait. It's not like it's the BIGGEST issue with dolphin anyway.
I'll put it another way.
You don't want to sort by language key content anyway. To do so would require the country list be read in and processed by php. The sorting due to it's level of complexity would drastically increase the length of time it takes to do a sort.
People complain about dolphin being slow already, and if your going to request features that will slow it down even more, then i don't really think they will consider doing it.
