  - Set `NNN_OPENER` to let a desktop opener handle it all. E.g.:
        export NNN_OPENER=xdg-open
        export NNN_OPENER=gnome-open
        export NNN_OPENER=gvfs-open
  - Selective file associations (ignored if `NNN_OPENER` is set):
    - Associate plain text files (determined using file) with vi
    - Associate common audio and video mimes with mpv
    - Associate PDF files with [zathura](https://pwmt.org/projects/zathura/)
    - Removed `less` as default file opener (there is no universal standalone opener utility)
    - You can customize further (see [how to change file associations](#change-file-associations))
  - `NNN_FALLBACK_OPENER` is the last line of defense:
    - If the executable in static file association is missing
    - If a file type was not handled in static file association
    - This may be the best option to set your desktop opener to
  - To enable the desktop file manager key, set `NNN_DE_FILE_MANAGER`. E.g.:
        export NNN_DE_FILE_MANAGER=thunar
- Optimization
  - All redundant buffer removal
  - All frequently used local chunks now static
  - Removed some redundant string allocation and manipulation
  - Simplified some roundabout procedures
  - Compiler warnings fixed
  - strip the final binary
