[Request] Option to warn when there are hidden files

[dacid44]

Would it be possible to add an option to warn if there are hidden files without displaying them? I've many times been in a situation where I'm looking for a file, but I can't find it because I forget to specify --all. It would be great to have an option (likely most used in an alias) to display a warning like "...5 hidden files", to be able to easily tell when there are hidden files without taking up the space of actually displaying all of them when they're irrelevant.

I've got a fair amount of Rust experience, I'd probably be willing to work on a PR for this.

(Please excuse me if this is already a feature. I looked through --help and the README.md but didn't find anything, but it's absolutely possible I just missed something.)

Thanks!

Are you serious? wtf

Is there something major that I'm missing here?
