Hello!

After working with script for a while (nice work btw!) I miss some basic functions that I eventually implemented (in a quick and dirty way) for myself.

Most of them have to do with directory manipulation, like "list of files in a directory", "list of directories in a directory" as well as "by date" variants which are super useful when we need, for instance, to find the N newest files on a dir?

Would there be interest in PRs with these?
