- Only support for Console is built-in to Nautilus currently. Other terminals install their own Nautilus extension that adds them to the context menu. That’s what Gnome Terminal does.
- xdg-terminal-exec would do that, and was worked on for Nautilus Add xdg-terminal-exec integration (!1781) · Merge requests · GNOME / Files · GitLab , but as you can read in the comments there xdg-terminal-exec was a stop-gap solution and XDG Intents is instead what will fill this need. A recent update talks also about how it works for terminals and which GNOME components already support it: XDG Intents Updates
I prefer Ptyxis and same as you removed Console and Gnome Terminal. My solution was to write a short Nautilus extension that adds “Open in Ptyxis” to the context menu: jakedane/nautilus-ptyxis: Nautilus extension to open directories in Ptyxis - Codeberg.org. It should be easy to compile, at least it is on Arch Linux. Compiling on other distros may require changes to the build command.
