- Associate PDF files with [zathura](https://pwmt.org/projects/zathura/)

- Removed `less` as default file opener

### Filters
|
||||
|
||||
Filters support regexes to display only the matched entries in the current directory view. This effectively allows searching through the directory tree for a particular entry.
|
||||
|
||||
Filters do not stack on top of each other. They are applied anew every time. An empty filter expression resets the filter.
|
||||
|
||||
If nnn is invoked as root the default filter will also match hidden files.

||||
