Understood. I do agree a single software can't fit all use cases. nnn avoids destructive operations like delete. However, one can always spawn a terminal in the current directory using `!` and delete the files from the shell.

Not really. `ls` a dir with 20K files and see the difference with nnn. ;) And then, nnn is more about navigation. Try shortcuts like `-`, `&`, `~` (tilde), `....` and of course the `navigate-as-you-type` mode. Looking for a specific file? Try filter mode with search-as-you-type.
