I have all of them, and many more. The question was what should be added by default.

I've been using GNOME for years and have never heard of it.

How can I make it a default?

When I open a new Nautilus instance, it’s always a new window. There’s no way to open a tab, not a window. The only way I know is to press ctrl + t in the app. Or open a new window, new tab, drag the tab I need to window-1, and close just opened tab-2 on the window-2.

I have automations that open new Nautilus windows with given paths (e.g. all the directories I need for a particular project I’m working on), all of them are opened with new windows. When that’s just one new window it’s irritating, but manageable. But if I open even three new paths that way, I have three new windows, which is useless and irritating even on my huge 27” Quad HD display. On top of that, Nautilus likes to crash if I suddenly open three new windows. (My computer is plenty powerful.)

Last time I checked (which wasn’t too long ago, half a year or so) that wasn’t a thing, and the developers stated it’s a complication they never plan implementing. All I need is just one fucking cli parameter, not even a ‘open tabs by default’ checkbox.

I assume folks who downvoted me are not aware of this, obviously.

Dolphin has this and works perfectly. But it’s too bloated to my liking. I really like Nautilus, so I just live without this feature and manage my work projects with CLI file managers. (Usually ranger, but not limited to it.)
