What a terrible application it is, that "Software Sources" in Mint 15. Woe unto the poor user whose local mirrors are at the end of the list. The poor soul has to either wait unending hours or scroll down really quickly and click on the mirror they want. And that assumes a) the user can make out the ridiculously small flags, and b) it doesn't crash out every few minutes when a server takes too long to respond. It's usefulness is zero, except as a thumb-twiddling time sink, in which case it rates 10 out of 10.
Please fix the horrible thing.
Making the speed test optional, and including country names instead of tiny icons would help, as would being able to select the region that the speed test applies to.
