Add option to hoist folders to top of list

[iLynxcat]

This is a good feature request, probably as a toggleable option. Likely by default we'll sort as expected on Windows and use regular sorting on macOS, not sure how popular Linux file managers do this (all I know is ls sorts mixed like the Finder on macOS does, lol)
