I'm new here, and I hope this is the right place to suggest something like this. For years, I was a heavy macOS user, using it exclusively for work (web development). However, since a year ago, I've been using Ubuntu (the default for all web developers in my company), and I really enjoy it. There's just one thing I miss from macOS: the Miller columns in the file manager. They are so much more efficient to use!
I know that I can change operating systems as long as it's Debian-based. Zorin OS looks great, and I'm seriously considering adopting it as my work OS.
It would be amazing if Miller columns could be added to it! That would make it my dream OS!
I'm aware that Elementary OS has Miller columns, but honestly, I don't think it's a very 'mature' OS.
Never seen it that before, I must admit. Perhaps Dolphin file browser can do this? Note: It's KDE/QT app and may not blend to well with Zorins Gnome/GTK environment.
Zorin OS and Ubuntu uses what the Gnome DE comes up with and put their own modification to it. You can try to ask the Gnome devs. to add it to Nautilus. I don't know how difficult it is for such task. But be warned they have their own opinion on how Gnome should work and what's best for its users - despite what the users think.
Thanks for the correction - I edited the post above. This is what happens when I lazily copy and paste a repeating command instead of typing each out. I missed the typo.
I was about to throw in another correction but what do you know, you can do both add-apt-repository as well as apt-add-repository. Always learning something new...
