[Feature] Allow user to chose lowercase directory names

Hi,

Awesome tool, love the idea.

It'd be nice to allow the choose between upper and lower case output names of the folders, I know this could be down with -st, but a convenience flag would be ... convenient ;)

I've noticed that the calling "classifier" command without any arguments and then attempting any moves forces an uppercase first character. Any other moves after the fact work as intended. I think that removing the initial classifier call might solve this issue.
