[FEATURE] Search and/or filter for file(s)/directory(s) within subdirectory

[iwconfig]

Hiya!

Like the title says. I want to limit my search. Currently the search result is global so if I have multiple names of the same name in different locations I get all of them and I don't know which one to pick. Also if there are a lot of file it can be difficult to find it in the search result. And if there's a lot of files in the directory there might be a need to search/filter the view to find that file which happens to be placed at the bottom of the list, but that would require all files to have loaded in the directory view.
