Thanks @Beatlemaniac19, I'll check on that. I think I remember that issue from a long time ago, but it may not be an easy one to solve, if I recall correctly.
Per the number sorting, somewhere around the release of Vista, Microsoft introduced a much more complicated sorting algorithm that does sort entire numbers instead of just characters. I agree that it would be an improvement (though it's an irritatingly difficult thing to tackle). I can't say it's a high priority, but I will add it to my list.
