Here's how it looks like ( it's my first SwiftUI code ever )

Thank you for your pull request!
Firstly, I think that it should be "Filter by" or "Filtered by" instead of "Filter option" and "Name" instead of "Alphabetical".

Secondly, segmented control is too large and I recommend to put Spacer() between text and segmented control.

Finally why does the directory list view look like it has a container with right & bottom borders?
