Support opening/revealing files in third-party file managers

[seedds]

Feature request

Cardinal currently supports opening the highlighted result with Cmd+O and revealing it in Finder with Cmd+R. It would be useful to allow users to open or reveal files in other file management apps as well, such as Double Commander, Commander One, Path Finder, ForkLift, etc.

Motivation

Some users use third-party file managers as their primary file navigation tool instead of Finder. When searching files in Cardinal, being able to reveal a result directly in the preferred file manager would make the workflow smoother and avoid switching back to Finder manually.

Suggested behavior

Add a setting in Preferences to choose the file manager used for “Reveal in file manager”.

Possible options:

• Finder, default/current behavior
• Double Commander
• Commander One
• Custom application path or bundle identifier

Then Cmd+R could reveal the selected file using the configured app.

Possible implementation ideas

• Keep Finder as the default to preserve current behavior.
• Add a configurable “Reveal in” app preference.
• For third-party apps, pass the selected file path to the configured application, or use app-specific URL schemes / AppleScript where available.
• Optionally add a context menu item such as:
  • Reveal in Finder
  • Reveal in Preferred File Manager
  • Open With...

Use case

I use a third-party file manager for daily file operations. After finding a file in Cardinal, I would like to jump directly to that file in my preferred file manager instead of Finder.

Would add an "Open With" in the right-click menu helpful?

Yes, that would be very helpful.
