Double Commander vs nnn

You can use same tool in all desktop OS environments.

If the developer loses interest there is at least the possibility that someone else will pick up the torch.

Lots of options allow you to configure DC the way it suits you best: Tools, Fonts, Colors, Hotkeys, Mouse, Fileviews, Plugins, Layout, Toolbars, Tabs, Icons etc.

Save shortcuts to folders. Organize them in a treeview with submenus. Define a name and sorting for each entry.

so you can use documentation from Total Commander for writing plugins. WCX (packer), WDX (content), WFX (file system), WLX (lister).

For instance, the 'Settings | Layout' pane is quasi-identical to TCs.

Although it is lightweight and simple to use, it can do very sophisticated tasks, like copying files from directories which have a certain extension or file size or have a certain text pattern in them. Also, it's very customizable and stable.

It's all a matter of perspective. I'm not for an argument about IDE's, frameworks etc, but to me that's a big plus. I think it should be a tie, it's either a pro or a con or should that be neither a pro nor a con. It just depends on context.

Default options and navigation is simple to grasp.

Save and resume sessions.

Allows for quick switching between nnn and the terminal.

The file manager has recently added support for preview hovered files using various methods.

However, it requires some prior knowledge of inner workings of Linux and there are no tutorials (yet). NNN author is making up for this by actively responding to GitHub issues.
