sort orders are computer-friendly, user-antagonistic

[TallTed]

With A2Z, all upper-case currently come before all lower-case -- i.e., A comes before Z comes before a comes before z -- i.e., sorting is apparently by code-point order.

Mixed-case alpha-order is more typically human (i.e., A is treated as identical to a [and to à, and to Å, etc.] for sorting). Any way this can be enabled?

A related but probably very different challenge -- all "files" are listed before all "folders". Any way to have these intermingled when sorting by name/date?
